A roulette wheel has 38 slots, 18 are red, 18 are black, and 2 are green.You play five games and always bet on red. a) How many

Mariana [72]

Answer:

a) 2.35 games.

b) Therefore, the probability is P=0.0229.

c) Therefore, the probability is P=0.71.

Step-by-step explanation:

We know that a roulette wheel has 38 slots, 18 are red, 18 are black, and 2 are green.You play five games and always bet on red.

Therefore, we have

$p=\frac{18}{38}=0.47\\\\q=\frac{20}{38}=0.53\\$

a) We can you expect to win 5·0.47= 2.35 games.

b) We calculate the probability that you will win all five games.

$P=C_5^5\cdot p^5\cdot q^0\\\\P=1\cdot 0.47^5 \cdot 0.53^0\\\\P=0.0229$

Therefore, the probability is P=0.0229.

c) We calculate the probability that you will win three or more games.

$P=1-C_2^5\cdot 0.47^3\cdot 0.53^2\\\\P=1-10\cdot 0.47^3\cdot 0.53^2\\\\P=1-0.29\\\\P=0.71$

Therefore, the probability is P=0.71.
