A basketball player has a 40% shooting average from the freethrow line. If she takes two free throws, estimate the probability that she will make both of them. Use the following list of digits which was taken from a table of random numbers. Let the digits 03 represent a made free throw and let the digits 49 represent a miss. Start at the top left of the table and move all the way across to the right of the table before moving down to the next row.

The probability of making two in a row is (2/5)^2 = 4/25.
I have no idea what the (A)  (D) part of your question is all about.
You could use the numerical entries to compute the actual fraction of free throws made, and the fraction of consecutive pairs of free throws made.
45 of 100 free throws were made (45%), which is better then the supposed average.
