Question

Please help with probability question, show all steps and work

If we spin a roulette wheel 760 times, what is the expected # of greens, reds, and blacks that we will see? green red ac Here are the relevant facts about roulette: A roulette wheel has the following 38 slots that the ball can fall into: number 0 color green green red black red black red black red black red black red black red black red black red black red black red black red black red black red black red black red black red black red black 4 9 10 12 13 14 15 16 17 18 19 20 21 23 24 25 26 27 28 29 30 31 32 34 35 36

Explanation / Answer

Solution:-

Total number of greens = 2

Total number of reds = 18

Total number of black = 18

Probability of getting red = 18/38 = 0.4737

Probability of getting black = 18/38 = 0.4737

Probability of getting green = 2/38 = 0.053

After rolling 760 times

Expected number of green = 0.053 × 760 = 40

Expected number of red = 0.4737 × 760 = 360

Expected number of black = 0.4737 × 760 = 360
