A certain board game requires the roll of 3 standard dice to determine the outcome of a battle. what is the probability that at least one of the dice will show an even number?

This is the concept probability and statistics;

A die has 6 sides, the probability of die landing on one specific number (1,2,3,4,5,6) is given by

P (x) = 1/6

The probability of that number being an even number (2,4,6) is:

1/6*3=1/2

Thus given that 3 die were rolled at a go, the probability of getting at least an even number will be:

1/2.

This is because it will take the probability of getting an even number when one die is tossed
