ConceptSimple Problems on Single Events

#### Question

A pair of dice is thrown. Find the probability of getting a sum of 10 or more, if 5 appears on the first die.

#### Solution

In throwing dice, total possible outcome ={1,2,3,4,5,6}

n(s)=6

for two dice, n(s)=6xx6=36

Favorable cases where the sum is 10 or more with 5 on 1st die = {(5,5),(5,6)}

Event of getting the sum is 10 or more with 5 on 1st die = n (E)=2

Probability of getting a sum of 10 or more with 5 on 1st die =

(n(E))/(n(s))=2/36=1/18
