Answer 1

Answer:

Step-by-step explanation:

Hi

Here we go

Total outcomes will be 90

1. P(E)=No.of favourable outcomes/Total outcomes

P(E)=81/90=9/10

Here 81, because there are 81 nos which are two digit

2.P(E)=No.of favorable outcomes/Total outcomes

P(E)=9/90=1/10

Here 9, because there are 9 square no between 1 and 90

3.P(E)=No.of favorable outcomes/Total outcomes

P(E)=18/90=1/5

Here 18, because there are 18 no.divisible by 5 between 1 and 90

Hope it helps
