Thank you for the opportunity to help you with your question! the solution is as such:

The total no. Of selections can be 20 C 5. 

And the favourable cases are 8 C 5.

So probability = (8C 5) / (20 C 5)

= 56/ 15504    = 0.0036 

Here c stands for combination.

Please let me know if you need any clarification. I'm always happy to answer your questions.awaiting a positive feedback. thank you.
