Question

A dice is thrown once. Find the probability of getting a number less than 8. 

Sum

Solution

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

n(S) = 6 

On a dice, numbers less than 8 = {1, 2, 3, 4, 5, 6} 

n(E) = 6  

Probability of getting a number less than 8

= `(n(E))/(n(S))`

= `6/6`

= 1
