There are 2 coins, 1 and 2. Each has two possibilities, H or T.
The possibilities are:
1H, 2H
1H, 2T
1T, 2H
1T, 2T
Each possibility has an equal chance of happening.
The chance of tossing at least one head is 3/4.

What is the probability of tossing at least three heads if a fair coin is tossed four times?
It is 0.3125
If 3 coins are tossed simultaneously the probability of getting at least 1head is?
3/8
Probability of getting 1 head tossing two coins?
By tossing two coins the possible outcomes are:H & HH & TT & HT & TThus the probability of getting exactly 1 head is 2 out 4 or 50%. If the question was what is the probability of getting at least 1 head then the probability is 3 out of 4 or 75%
Three fair coins are tossed- whats the probability of tossing at least one head?
The chance for each toss is 1/2. The chance of all three flips being tails is 1/2 * 1/2 * 1/2 = 1/8. So the probability of at least one head is 7/8.
What is the probability of of tossing heads on the first 6 tosses of a fair coin?
The probability of tossing heads on all of the first six tosses of a fair coin is 0.56, or 0.015625. The probability of tossing heads on at least one of the first six tosses of a fair coin is 1 - 0.56, or 0.984375.
What is the probability of tossing at least three heads if a fair coin is tossed four times?
It is 0.3125
What is the probability that at least one coin will be tails?
The answer depends on how many coins were tossed.
If 3 coins are tossed simultaneously the probability of getting at least 1head is?
3/8
You toss 3 coins what is the probability that at least 1 tail is tossed?
1/6
When tossing 4 coins simultaneously find the probability that at least 1 head is showing?
It is 15/16.
Probability of getting 1 head tossing two coins?
By tossing two coins the possible outcomes are:H & HH & TT & HT & TThus the probability of getting exactly 1 head is 2 out 4 or 50%. If the question was what is the probability of getting at least 1 head then the probability is 3 out of 4 or 75%
When tossing 5 coins simultaneously what is the probability that at least 1 head is showing?
Probability of no heads = (0.5)^5 = 0.03125Probability of at least one head = 1 - probability of no heads = 1 - 0.03125 = 0.96875
Three fair coins are tossed- whats the probability of tossing at least one head?
The chance for each toss is 1/2. The chance of all three flips being tails is 1/2 * 1/2 * 1/2 = 1/8. So the probability of at least one head is 7/8.
What is the probability of tossing at least one head with 3 coins?
3 coins can land in 8 different ways. Only one of these ways is all tails. So the probability of rolling at least one heads is 7/8 = 87.5% .
When tossing 5 coins simultaneously can you find the probability that at least 1 head is showing?
Probability not at least 1 head showing is when all 5 coins are tails: (1/2)5=1/32 Therefore probability at least 1 head is showing is 1-1/32=31/32
What is the probability of getting 6 heads in tossing 6 coins in 6 tosses?
The probability of tossing 6 heads in 6 dice is 1 in 26, or 1 in 64, or 0.015625. THe probability of doing that at least once in six trials, then, is 6 in 26, or 6 in 64, or 3 in 32, or 0.09375.
If nine fair coins are tossed what is the probability of obtaining at least one head and at least one tail using the complement formula?
255/256 (complement formula)
