There are 8 possible outcomes when a coin is tossed 3 times. Here they are:1. Heads, Heads, Tails.2. Heads, Tails, Heads.3. Tails, Heads, Heads.4. Heads, Heads, Heads.5. Tails, Tails, Heads.6. Tails, Heads, Tails.7. Heads, Tails, Tails.8. Tails, Tails, Tails.There is only one outcome that is heads, heads, heads, so the probability of three heads coming up in three coin tosses is 1 in 8 or 0.125 for that probability.

With 4 coins you have 24 (16) possibilities. If we wanted a specific coin to land 'tails' while the others landed 'heads' we would have one possibilty out of 16. Since we don't care which of the coins lands 'tails,' we have four chances in 16 or a 25 percent chance.

It means that if the coin were tossed an infinite number of times, half of the tosses would come up heads and half would be tails.

Half the time they will be the same, half the time they will be different. Half of the time that they're the same they will be heads, half the time they are the same they will be tails. It's your homework, YOU figure it out. The way I figure it. There are four options: 1) heads / heads 2) heads / tails 3) tails / heads 4) tails / tails By process of chance, one out of four times both coins will be heads/heads. Therefore 780/4 = 195 times.

When h=head, t=tails First toss: heads/tails (1h/1t) Second toss: heads/tails (2h/1h1t*2/2t) Third toss: heads/tails (3h/2h1t*3/1h2t*3/3t) Fourth toss: heads/tails (4h/3h1t*4/2h2t*6/1h3t*4/4t) In short, 1+4+6+4+1=16 Chances of getting 2 heads and 2 tails = 6/16 * 100% = 37.5%

Coins do not have numbers, there is only the probability of heads or tails.

The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.

T = H + 10 T + H = 42 so T = 26, H = 16 Therefore Prob(T) = 26/42 = 0.6190

The number of sequences is 27 or 128.

There are 4 events: 3 heads, 2 heads 1 tail, 1 head 2 tails, and 3 tails.

The chances if someone winning a coin toss are 50/50. Depending on which side of the coin one chooses such as head, when the coin is tossed there is a 50 percent chance that the coin will land on either heads or tails.

only about 75% because very often it is not equal The probability of 3 heads and 3 tails is 0.3125

The experimental probability of a coin landing on heads is 7/ 12. if the coin landed on tails 30 timefind the number of tosses?

The probability is 0.25.Look at it this way--if you toss a coin twice, there are four equally-probable outcomes:tails, tailstails, headsheads, tailsheads, headsSo the probability of heads twice in a row is one in four, or 25%.the chance of tossing heads is 1/2 (50%) The chance of tossing the next heads is 1/2 (50%) 1/2 x 1/2 = 1/4 (25%)

No - it is "can't make heads or tails of it." It means you cannot understand something at all, as if you cannot tell whether a coin has landed heads up or tails up.

0.5, 1/2, 50% The probability for heads versus tails does not change based on the amount of times the coin is tossed. It will always be a 50% chance.

Heads+Heads ; Heads+Tails ; Tails+Tails

The probability of getting two tails in the first two is 1/4. And it does not matter how many more times the coins are tossed after the first two tosses.

These are independent one has no bearing on the other

lets get some facts odds of head on 1 coin 50% or evens odds of no head 50% or evens the possible results vary from 1 coin to 2 coins. 1 coin has 2 results heads or tails 2 coins have 4 results. heads heads, tails tails, tails heads, heads tails. each outcome has a probability of 25%. for the question we remove the heads and tail probability and we have 2 outcomes with heads and one without. so 2 to 1 chance or 33.3333 recuring chance.

Two coins tossed sample space is (H=Heads, T = Tails) as follows. HH, HT, TH, TT is the sample space.
