Answer 1

Answer:

Hey mate here is your answer.//

Step-by-step explanation:

Given: Two coins are tossed simultaneously.

To find: the probability that the second coin would show a tail given that the first coin has shown a head.

Sol: The sample space for two coins is {HH,HT,TH,TT}, n(S)=4

Favourable outcomes for the first coin head and second coin showing tail are HT, n(E)=1 .

Hence, the probability that the second coin would show a tail given that the first coin has shown a head is:  

n(S) /n(E),

​  

=1/4,  

=0.25.//
