You can put this solution on YOUR website! You roll a cube which has the numbers 17, 20, 23, 26, 28, and 29 on it. You then spin a spinner which has 6 sections. The letters on the spinner are G, E, F, K, C, and H. What is the probability of picking an E and not a 20?
-----
These are independent events, so
P(E and not 20) = P(E)*P(not 20) = (1/6)*(5/6) = 5/36
