Among the four equally likely outcomes, three are favorable to “tails” and one of those three is favorable to “fair”. Hence Pr(fair∣tails)=1/3.

Explanation –
You are given a flash light which takes 2 good batteries to run, and 8 batteries, 4 good ones and 4 used up. What is the minimal number of trials needed to get the flashlight running?
Total batteries = 8.

Out of the 8 batteries, only 4 are in working condition.

We need 2 good batteries to run.

Lets try to divide the 8 batteries in a group of 3.

8 = 3 + 3 + 2.

Group 1 = 3 batteries,
Group 2 = 3 batteries,
Group 3 = 2 batteries.

Now you have made sure that one of the group has two working batteries.

How many combinations are possible for each group?

Group 1: B1 B2 B3.
Possible combinations → B1B2 , B2B3 or B1B3.
Total combinations = 3.

Group 2: B4 B5 B6.
Possible combinations → B4B5 , B5B6 or B4B6.
Total combinations = 3.

Group 3: B7 B8.
Possible combinations → B7B8.
Total combinations = 1.

Adding all the combinations = 3 (Group 1) + 3 (Group 2) + 1 (Group 3) =7.

Hence, minimum number of trails needed = 7.
