Hello aspirant,

Hope you are doing well,

When the dice is tossed thrice,

The outcomes we get is

={1,2,3,45,6}

Odd numbers = {1,3,5}

The probability of getting odd number at first throw

= 3/6 = 1/2

The probability of getting even number in a single throw

= 3/6 = 1/2

The probability of getting even number three times

= 1/2 × 1/2 × 1/2 = 1/8

The probability of getting an odd number at least once = 1 - the probability of getting an odd number in none of throw

= 1 - probability of getting even number three times

= 1 - 1/8

= 7/8     is the answer.

Hope this information helps,

Good luck
