Answer 2

Answer:

1. coin has two sides head (H) and tail(T). Hence, the probability of getting at least 2 heads= ½.

explain

When three coins are tossed simultaneously, the total possible outcomes are {(H,H,H) , (H,H,T) , (H,T,H) , (H,T,T), (T,H,H), (T,H,T), (T,T,H), (T,T,T)}.

The total no. of outcomes = 8

For tail appears on middle one

The favorable outcomes are

{(H,T,H), (H,T,T), (T,T,H), (T,T,T)}.

No. of favorable outcomes = 4

Therefore, probability of getting tail on middle one = 4/8 =1/2
