5, 7, 9, 12, 14, 16,......
In the game Roulette, a ball spins on a circular wheel that is divided into 38 arcs of equal lenght, numbered 00, 0, 1, 2, ... , 35, 36. The number on the arc on which the ball stops is the outcome of one play of the game. The numbers are also colored as follows:
1, 3, 5, 7, 9, 12, 14, 16, 18, 19, 21, 23, 25, 27, 30, 32, 34, 36 are red,
2, 4, 6, 8, 10, 11, 13, 15, 17, 20, 22, 24, 26, 28, 29, 31, 33, 35 are black,
0, 00 are green

Define the following events:

These are the values i got not sure if they are right

A: Outcome is an even number (0 and 00 are considered neither odd nor even) = 9/19
B: Outcome is a red number = 9/19
C: Outcome is a green number = 1/19
D: Outcome is a low number (1-18) = 9/19

(a) P(C) = 1/19
(b) P(AnB) = 4/19
(c) P(BuCuD) =

a and b are right i dont know how to get c

Thank you!

-
make into disjoint sets and add up
(c) P(BuCuD) = P(B) + P(C) + P(LOW BLACK)
= (18+2+9)/38 = 29/38 <---------
