PLEASE ANSWER!!!Two dice are thrown. Find the probability of the following events:Event A : The product of the numbers on their upper faces is 10.Event B : The sum of the numbers on their upper faces is multiple of 9. |

Answer» <P> Let A &B be the FAVORABLE event then A= {(2,5),(5,2)} N(A)=2 since n(S)=36 so,p(A)=n(A)/n(S) =2/36 =1/18. Similarly, B= {(3,6),(4,5),(5,4),(6,3)} n(B)=4 We KNOW n(S)=36. so,p(B)=n(B)/n(S) =4/36 =1/9. Hope it will help you |
