Step-by-step explanation:

The possible outcomes are 25

1,1 1,2 1,3 1,4 1,5

2,1 2,2 2,3 2,4 2,5

3,1 3,2 3,3 3,4 3,5

4,1 4,2 4,3 4,4 4,5

5,1 5,2 5,3 5,4 5,5

a) the possible pairs are 25

b) the probability of both no being odd

= Possible outcomes÷ total no of outcomes

=3/25

c) the probability of both no being even

= Possible outcomes÷total no of outcomes

=4/25

d)

=Possible outcomes÷total no of outcomes

=12/25
