Question

A fair coin is flipped twice. H is recorded for heads and T for tails after each flip. The notation for conditional probability is ​P(H on 2nd flip|H on 1st flip)​. Which notation is the probability of the two events being not independent?

Answer 1

Answer: P(H on 2nd flip|H on 1st flip)=P(H on 2nd flip)

Explanation:

Answer 2

The Notation for each event Not been independent = P( HT ) or P( TH )

Explanation:

when A fair coin flipped ; P( H ) = 0.5 and P( T ) = 0.5

Hence when it is flipped twice the possible outcome = 4

= HH , HT , TT, TH

Since Notation for conditional probability = P ( HH ) this shows that each flip is independent

The Notation for each event Not been independent = P( HT ) or P( TH )
