sum. no of times
2. 14
3. 30
4. 42
5. 55
6. 72
7. 75
8. 70
9. 53
10. 46
11. 28
12. 15


if 2 dices are thrown again once,find P(E)
a.a sum of 3
b. less than or equal to 5
c.sum more than 10
d.between 8 to 10

Answer 1

1.no. of outcomes = 500
favourable outcomes = 30+72+53+15
=170
probability = 170/500
=17/50

2.favourable outcomes = 14+30+42+55
=141
probability = 141/500

3. favourable outcomes = 28+15
= 43
probability= 43/500

4. favourable outcomes =53
probability = 53/500
