Question

Three coins are tossed simultaneouly. Find the probabiity that tail appears on the middle coin​

Answer 1

Step-by-step explanation:

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

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

so the probability of getting a tail is 1/2

mark me as brainiest

Answer 2

Answer:

1/2

Step-by-step explanation:

because middle coin has 1 tail and 1 head no....

so the probability of tail is 1/2
