Question

in a random experiment of tossing two coins two points simultaneously find the the probability of getting exactly one head and one tail.question 4​

Answer 1

Answer.getting 1 head and 1 tail:

Let E9 = event of getting 1 head and 1 tail. Then,

E9 = {HT, TH } and, therefore, n(E9) = 2.

Therefore, P(getting 1 head and 1 tail) = P(E9) = n(E9)/n(S)= 2/4 = 1/2.
