Question

The probability of getting 3 heads and 2 tails in tossing 5 coins is

(a) 1/16
(b) 5/16
(c) 7/16
(d) None of these​

Answer 1

Answer:

D

LOL!! Believe me it's the right answer

Answer 2

The number of possible outcomes for getting 3 heads and 2 tails is 5!/(3! x 2!) = (5 x 4)/2 = 10. Thus, the probability of getting 3 heads and 2 tails in 5 flips is (1/32) x 10 = 10/32 = 5/16

therefore the answer is option b)5/16

hope it helps you
