What is the probability of tossing a coin three times and getting it on heads each time?
Each toss has a 1/2 probability of getting heads. Each toss is an independent event. So three heads in a row (heads AND heads AND heads) would have a probability of:1/2 * 1/2 * 1/2 = (1/2)^3 = 1/(2^3) = 1/8 = 12.5%
When tossing a fair coin the probability of getting three heads in a row is?
In a large enough number of tosses, it is a certainty (probability = 1). In only the first three tosses, it is (0.5)3 = 0.125
What is the probability of tossing a dice and getting 3 sixes in a row?
The probability of tossing a die and getting three 6's in a row is (1/6)3, or about 0.004630.
What is the probability of getting heads three times in a row when tossing a coin?
Ideally, the probability of getting any specific combination of length n is 0.5n = 1/2n. For n = 3, this is 0.125 = 1/8.
When a coin is tossed three times what is the probability of getting at most two heads?
The opposite of getting at most two heads is getting three heads. The probability of getting three heads is (1/2)^2, which is 1/8. The probability of getting at most two heads is then 1 - 1/8 which is 7/8.
What is the probability of not tossing three heads with three fair coins?
The probability of something NOT happening is the complement of the probability of something happening. Since the probability that you DO have 3 heads is 1/8 (that is, 1/2 cubed), the complement is 1 - 1/8 = 7/8.
What is the probability of tossing exactly three tails?
well it depends on what you are tossing, if its a coin then no. it can be heads too. it would have to be a great coincidence for it to be all tails, but thats why the word probability comes in meaning that there is more than one outcome
What is probability of at least 2 heads on tossing 3 coins?
There are 8 permutations of three coins. Of these, 3 of them have two heads, so the probability of tossing two heads on three coins is 3 in 8, or 0.375. However, you said, "at least", so that includes the case of three heads, so the probability of throwing at least two heads is 4 in 8, or 0.5. T T T T T H T H T T H H * H T T H T H * H H T * H H H *
What is the probability of getting a run of three consecutive heads before a run of two consecutive tails when tossing a fair coin over and over?
The probability of getting a head first time is one out of two, or a half. The probability of getting a head the next time is still one out of two, so the combined probability is one quarter. Similarly, one eighth is the probability of getting three in a row; but the pattern does not end there, the probability of getting a tails the next time is STILL one in two, so that is a one in sixteen chance of that run, the probability of the entire sequence is therefore one in thirty-two.
What is the probability of rolling a three or a six on a die then tossing a heads on a coin?
First event is to roll a 3 or 6 on a die, which gives you a probability of 2 out of 6. Second event is tossing a heads on a coin, so a probability of 1 out of 2. Since both chances are not related, you can multiply both chances: 2/6 times 1/2 = 1/6 = 0,166666...
What is the probability of getting heads more than once if you flip a coin three times?
For 3 coin flips: 87% chance of getting heads at least once 25% chance of getting heads twice 13% chance of getting heads all three times
What is the probability of tossing two 6-sided die three times and getting an even number all three times?
The probability of getting an even sum on two dice is 18 in 36 or 1 in 2 or 0.5. The probability of doing that three times in a row is 0.53 or 0.125.
What is the probablity that the sequence will be heads-heads-heads if you toss a coin 3 times?
the probability of getting heads-heads-heads if you toss a coin three times is 1 out of 9.
What is the probability of getting a simple event of three heads and one tail after tossing a coin four times?
4/16 or 1.44/16 or 1.44/16 or 1.44/16 or 1.4
What's the probability of tossing a 6-sided die three times and getting an even number all three times?
Each time you toss the die the probability of rolling an even number is 3 out of 6 or 1/2. So, the probability of tossing three consecutive even numbers is (1/2)3 = 1/8 = 0.125, which is one chance in eight.
What is the probability of getting three or fewer heads on eight tosses of a coin?
It is 93/256 = 0.363 approx.
What is the probability of getting three heads if you flip a coin five times?
The probability of any 1 result of tossing a coin 5 times, for example HHTHH or TTTTH, is 1/2^5 = 1/32. To find out how many of these results involve getting 3 heads, say HHHTT or HHTHT, we use the calculation 5!/(3!*2!), which = 10. Finally we multiply these 2 results to get 10/32 = 5/16.
A coin is tossed five times find the probability of getting exactly three heads?
Since a coin has two sides and it was tossed 5 times, there are 32 possible combinations of results. The probability of getting heads three times in 5 tries is 10/32. This is 5/16.
What is the probability that a coin that is tossed 10 times what is the probability of it landing on heads 10 times?
The probability is 0.09766%.Each toss has a ½ chance to be heads. To combine probabilities use multiply them. So the probability to get two heads out of two tosses is ½ * ½, and three heads out of three tosses is ½ * ½ * ½. So the exact answer is 0.5^10
What is the probability of a coin tossed five times to get three heads?
Each coin toss is a Bernoulli trial with a probability of success of .5. The probability of tossing heads exactly 3 times out of five is3 ~ Bin(5, 1/2), which equals(5!/(3!(5-3)!))(0.5^3)(1-0.5)^(5-3), which is 0.3125.
What is the probability of getting all heads or all tails if you flip a coin three times?
The probability of getting all heads if you flip a coin three times is: P(HHH) = 1/2 ∙ 1/2 ∙ 1/2 = 1/8. The probability of getting all tails if you flip a coin three times is: P(TTT) = 1/2 ∙ 1/2 ∙ 1/2 = 1/8. The probability of getting all heads or all tails if you flip a coin three times is: P(HHH or TTT) = P(HHH) + P(TTT) = 2/8 = 1/4.
What is the probability of one heads and two tails?
In three tosses, the probability is 3/8.
What is the probability of tossing three coins and having all of them show tails?
When we toss a coin getting head or tail have equal probability of 50% - that is, out of the two possible outcomes getting the specified one becomes 1/2 probability. When we toss three coins, the probability of getting all the coins showing tails is given by (1/2) * (1/2) * (1/2) equal to 1/8 or 12.5 % chance. Alikban
You are tossing three coins and want to determine the probability for getting at least one head?
Pr(At least one head in three tosses) = 1 - Pr(No heads in three tosses) = 1 - Pr(Three tails in three tosses) = 1 - (1/2)*(1/2)*(1/2) = 1 - 1/8 = 7/8 or 0.875 or 87.5%
How many possible outcomes when tossing 3 coins?
three heads two head, one tails one heads, two tails three tails
