Question 1.

What is the probability of getting an even number when rolling a fair 6-sided die? Class 9

Solution:

All possible outcomes = 1, 2, 3, 4, 5, 6

∴ Number of all possible outcomes = 6

Number of favourable outcomes = 3

P(even number)

$=\frac{\text { Number of favourable outcomes }}{\text { Number of possible outcomes }}=\frac{3}{6}=\frac{1}{2}=0.5$

∴ The probability of getting an even number is 0.5.
