Question

In a single throw of a dice, find the probability of getting 8.

Sum

Solution

Sample space = {1, 2, 3, 4, 5, 6} 

n(S) = 6 

There are only six possible outcomes in a single throw of a dice. If we want to find probability of 8 to come up, then in that case number of possible or favourable outcome is 0 (zero)  

n(E) = 0 

Probability of getting a 8 = P(S)

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

= `0/6`

= 0
