Step-by-step explanation:

Total cards= 23

Total outcome=12

i) possible even outcome=12/23

ii)odd nos.=12

Possible outcome= 12/23

iii) prime nos.=5

Possible outcome=5/23

iv) divisible by 5= 5

Possible outcome=5/23

v) divisible by 3=8

Possible outcome=8/23

vi) perfect square= 3

Possible outcome=3/23
