Answer:
16/81
Step-by-step explanation:
The program generates numbers from 2 to 10; this is 9 total possible values (2, 3, 4, 5, 6, 7, 8, 9, 10).
Out of these, there are 4 prime numbers: 2, 3, 5, 7
The probability of choosing a prime number once is 4/9.
The probability of choosing a prime number the second time is 4/9.
Together, the total probability is 4/9(4/9) = 16/81.
