Thread: Homework Help Please :D

Sita puts 5 balls in Box A and 4 Balls in Box B.
The balls are numbered.


Box A-balls numbered 1-5
Box B-balls numbered 1-4

What is the probability that both balls have odd numbers?




I have done some working out and i think the answer may be 3/10
Can anyone please confirm this for me and tell me how they got to that answer.

Thankyou.
