Question

In a single throw of a dice, find the probability of getting a number not greater than 4.

Answer 1

Sample space = {1, 2, 3, 4, 5, 6} 

n(s) = 6

E = event of getting a number not greater than 4 = {1, 2, 3, 4} 

n(E) = 4 

Probability of a number not greater than 4 = ${\displaystyle \frac{n\left(E\right)}{n\left(s\right)}=\frac{4}{6}=\frac{2}{3}}$
