Question

A coin and a die are tossed. State sample space of following event.
B: Getting a prime number.

Answer 1

When a coin and a die are tossed the sample space S is given by
S = {H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}
∴ n(S) = 12
Let B: Getting a prime number
B = {H2, H3, H5, T2, T3, T5}
∴ n(B) = 6.
