http://wiki.answers.com/Q/If_you_Flip_four_coins_at_once_what_is_probability_of_2_head_and_3_tail" The probability of flipping four coins and getting 2 heads and 3 tails is ZERO 2 heads and 3 tails requires flipping FIVE coins.
1/16 * * * * * The correct answer, however, is 4/16 = 1/4.
3/8
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%
50/50
is it 50% or 100% dang, i just confused myself. what if you toss 3 coins all at the same time... what's the probability of getting a head then, is it > 100% ? Doh!

1/2 apex It does not matter what each prior flip's result was. Each flip has a probability of 0.5 heads or tails. Coins do not have "memory".
one out of four
3/8
1/4
50/50
7/8
Probability of H on the first flip = 1/2Probability of T on the second flip = 1/2Probability of both = (1/2 x 1/2) = 1/4 = 25%
It is 0.00540 approx.
you toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one head?
The probability is 3/4.
