Hey mate!

HERE IS YOUR ANSWER:

Total number of outcomes=11

1. Favourable outcomes=10,12,14,16,18,20
number of favourable outcomes=6
probability (even no.)=6/11

2 .Favourable outcomes=11,13,15,17,19
number of favourable outcomes=5
probability (odd no=5/11

3.Favourable outcomes =10,15,20
number of favourable outcomes=3
probability (multiple of 5)=3/11

4.Favourable outcomes =11,13,17,19
number of favourable outcomes=4
probability (prime no.)=4/11
