Question

A die is tossed thrice. Find the probability of getting an odd number at least once.

Answer 1

Probability of getting an odd number in a single throw of a die =

Similarly, probability of getting an even number =

Probability of getting an even number three times =

Therefore, probability of getting an odd number at least once

= 1 − Probability of getting an odd number in none of the throws

= 1 − Probability of getting an even number thrice
