Selecting random elements from an array. Assign selectedValues with numberSelected randomly selected elements from row array dataSet. Duplicate selections are acceptable. Hint: Use the randi function and an indexing array.
Ex: If numberSelected is 3 and dataSet is (74, 13, 1, 51, 6 ), then selectedValues might return [ 1, 74, 13 ].
Note: Successive "Runs' with the same arguments may return different results due to the random number generation. The ''Submit for Assessment' tests are configured to produce the same random numbers.
