Answer:

a. 16/52=4/13

b. 36/52=9/13

c.8/52=2/13

d.16/52=16/52

Step-by-step explanation:

a. even numbers are: 2;4;6;8. there are four sets in a deck. so we multiply these 4 even numbers with 4, which gives 16. so, answer is 16/52.

b. numbers less than 14: 2;3;4;5;6;7:8;9;10. multiplying by 4 again. this gives 36. so answer is 36/52.

c. perfect squares are: 4 and 9. so there are 2 perfect squares between 2 and 10 in deck of cards. again multiply it with 4. this gives 8. so answer is 8/52

d. prime numbers less than 20 in deck of cards are: 2;3;5;7. so, these are four primes. again multiplying with 4, this gives 16. so answer is 16/52
