Question

Three coins are tossed together, then the probability of getting at most one head is: -​

Answer 1

Answer:

If coins tossed three times then H be the head and T be the tail.

at most one head means 0 or 1

Let A be the probability of getting at most one head.

n(A) = {TTT, THT ,TTH , HTT }all these have one head and no heads = 4

n(S) = 8 { HHH, TTT , HTH , THT , TTH, HTT , HHT, THH}

P(A) = n(A)/n(S)

P(A) = 4/8

P(A) = 1/2
