Step-by-step explanation:
Given:
Number of questions (N) = 16
Number of easy questions (E) = 8
Number of medium-hard questions (M) = 5
Number of hard questions (H) = 3
Now, the probability of getting the first question as easy question is given as:

Now, probability of getting the second question as easy question is given as:

Now, probability that the first two contestants will get easy questions is given by the product of
. So,

Therefore, the probability that the first two contestants will get easy questions is 
3:5...added = 8
3/8(40 = 120/8 = 15 inches
5/8(40) = 200/8 = 25 inches
shorter piece is 15 inches
