Question

Two coins are tossed simultaneously. Write the sample space (S), n(S), the following event A
using set notation and n(A), where ‘A is the event of getting at least one head.’

Answer 1

Since two coins are tossed simultaneously,

S = {HT, TH, HH, TT}
⇒ n(S) = 4
A = {HT, TH, HH}
⇒ n(A) = 3
