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
