Answer 1

Heya !!

Here is your answer !!
______________________

Given ,
Total number of outcomes = 20
So !
1. Prime numbers from 1-20 ----> { 2 , 3, 5, 7 , 11, 13 ,17 ,19 }
Total = 8
So probability = No of outcomes possible / total numbers of outcomes =>> 8 / 20 = 2 / 5
____________________

2. An even numbered card from 1-20-->
{ 2, 4, 6, 8 , 10 , 12 , 14, 16 , 18 , 20 }
Total = 10
Probability = 10 / 20 = 1 / 2
_______________________

3. A card having numbers from 7 - 15
{ 7 , 8 , 9 , 10 , 11 , 12 , 13, 14 , 15 }
Total = 9
probability = 9 / 20
