Answer 2

Step-by-step explanation:

Total no of probabilities= 2^3 =8

for 2/1/0 heads probability is =7(only 1 left HHH)

So we cannot include HHH, because it contains 3 heads.

Here S = {TTT, TTH, THT, HTT, THH, HTH, HHT, HHH}

Let E = event of getting at most two heads.

Then E = {TTT, TTH, THT, HTT, THH, HTH, HHT}.

P(E)= n(S)/n(E)

= 8/7

Answer D

8/7

not 3/4 ok
