Answer:
230
Step-by-step explanation:
12 sections total
5 red, 4 green, the rest black
12-5-4 = 3 sections are black
3/12 = 1/4 of the sections are black
1/4 represents the probability of landing on black for one spin
(1/4)*921 = 230.25 which rounds to 230
We expect to land on a black section about 230 times out of 921 times total.
