Quantity A:
Possible cases in one roll: 2,3,5
Total possible outcomes: 1,2,3,4,5,6
Probability of obtaining a prime number on just one roll: \(\frac{3}{6}\)
Probability of obtaining a prime number on each of two rolls:
\(\frac{3}{6} * \frac{3}{6} = \frac{1}{4} = 0.25\)
Quantity B:
Possible cases in one roll: 1,2,4,6
Total possible outcomes: 1,2,3,4,5,6
Probability of obtaining them on just one roll: \(\frac{4}{6}\)
Probability of obtaining them on each of three rolls:
\(\frac{4}{6} * \frac{4}{6} * \frac{4}{6} = \frac{8}{27} = 0.29...\)
Quantity B > Quantity A

shouldn't 1 be excluded from the even numbers? this would make the probability 1/2^3 which is 1/8, making a>b
