Question

Two dice are rolled simultaneously find the probability of getting
1)number 1on both dice
2)sum of numbers obtained is 9
3) sum of numbers obtained is divisible by 4​

Answer 1

probability of getting 1 on both side is 1/36

sum of no.s obtained is 9 is 10/36

sum of no is divisible by 4 is .........

Answer 2

Answer:

.1........probability of getting 1 on both sides is 2 /12.. =1/6

2... sum of no. obtained is 9

favourable outcomes : 3,6; 6,3 ; 5,4 ;4,5 ;

probability is 4/12 =1/3

3...... sum of no divisible by 4 is 2,2 ;4,4 ;1,3 2,6;6,2 :6,6

probability is 6/12 =1/2
