The probability of rolling an even number (2, 4, or 6) can be found by adding the number of times 2, 4, or 6 was rolled and dividing by the total number of rolls:
P(even) = (18 + 11 + 21)/100 = 50/100 = 0.5
To express this as a percent, we multiply by 100:
P(even) = 0.5 x 100 = 50%
Therefore, the experimental probability of rolling an even number is 50%, or 0.5 as a decimal.
