Question

If two coins are tossed, find the probability of the following events.
(1) Getting at least one head.

Answer 1

Answer:

S = {HH, HT, TH, TT}

∴ n(S) = 4 i. Let A be the event of getting at least one head.

∴ A = {HT, TH, HH}

∴ n(A) = 3

∴ P(A) = n(A)n(S)n(A)n(S)

∴ P(A) = 3/4

Answer 2

Answer:

and the ans is probability is getting at least one head is 1times
