Answer 2

Explanation:

Number of possible outcomes=8

{(H,H,H) (H,H,T),(H,T,H),(T,H,H),(H,T,T),(T,H,T),(T,T,H) & (T,T,T)}

Number of favourable outcomes (at least 2heads)=4

Probability (at least 2headd)= Number of favourable outcomes/total number of outcomes

Probability(P)(at least 2heads)= 4/8=½

P(at least 2 heads)= ½

Hence, the probability of getting at least 2 heads= ½.
