Question

I’m not sure how to go about this question

Answer 1

for the first card selected, just multiply the number of cards of that kind over the total amount (30) by the new number of cards of that kind over the new total amount (29)

sample space is 10+6+9+5=30

7. 10/30*9/29=0.103

8. 6/30*5/29

9. 9/30*6/29

10. 5/30*9/29

11. 21/30*20/29

12. 19/30*18/29
