Suppose A[1], A[2], A[3], , A[n] is a one-dimensional array and n > 50. Required:
a. How many elements are in the array?
b. How many elements are in the subarray A[4],A[5],…,A[39]?
c. If 3 ≤ m ≤ n, what is the probability that a randomly chosen array element is in the subarray A[3],A[4],…,A[m]?
d. What is the probability that a randomly chosen array element is in the subarray shown below if n=39? A[⌊n/2⌋],A[⌊n/2⌋+1],…,A[n]
