The probability of landing on a 5 is much higher compared to a standard six-sided die. In order to calculate the probability of rolling a five, we need to add up the ratios.
Total Rolls = 100 + 50 + 30 = 180
Total Fives = 40 + 31 + 11 = 72
[tex]\frac{72}{180}[/tex] which reduces to [tex]\frac{2}{5}[/tex] or a 40% chance.
