An American roulette wheel has 38 slots with numbers 1 through 36, 0, and 00. Of the numbered slots, 18 are red, 18 are black, and 2- the 0 and 00- are green. When the wheel is spun, a metal ball is dropped onto the middle of the wheel. If the wheel is balanced, the ball is equally likely to settle in any of the numbered slots. Imagine spinning a fair wheel once. Define events B: ball lands in a black slot, and E: ball lands in an even-numbered slot. (Treat 0 and 00 as even numbers.)
(A) Make a two-way table that displays the sample space in terms of events B and E.
(B) Find P(B)
(C) Find P(E)
(D) Describe the event "B and E" in words. Then find the probability of this event.
(E) Explain why P(B or E) = P(B) + P(E). Then use the general addition rule to compute P(B or E).
