Answer 2

Step-by-step explanation:

Two coins are tossed. The sample set S will be {HH,HT,TH,TT}

(i) Let A be the event of getting two heads. Then event A will contain the outcome {HH}

P(A)= n(S)/n(A)= 1/4

(ii) Let B be the event of getting at least 1 tail. Then, B will contain the outcomes {HT,TH,TT}

P(B)= n(S)/n(B) = 3/4
