QuestionIn the game of roulette, a wheel consists of 38 slots numbered 0,00,1,2,,360,00,1,2, \ldots, 36. To play the game, a metal ball is spun around the wheel and is allowed to fall into one of the numbered slots. If the number of the slot the ball falls into matches the number you selected, you win $35\$ 35; otherwise you lose $1\$ 1. Complete parts (a) through ( g ) below.

(a) Construct a probability distribution for the random variable XX, the winnings of each spin. (Type integers or decimals rounded to four decimal places as needed.)

Studdy Solution
Construct the probability distribution table:
XP(X)351380.0263137380.9737\begin{array}{c|c} X & P(X) \\ \hline 35 & \frac{1}{38} \approx 0.0263 \\ -1 & \frac{37}{38} \approx 0.9737 \\ \end{array}
The probability distribution for the random variable XX is:
- P(X=35)=0.0263P(X = 35) = 0.0263 - P(X=1)=0.9737P(X = -1) = 0.9737
