To find:

The probability that the ball lands in an odd-numbered slot.

Given:

An American roulette wheel has 38 slots. Two slots are numbered 0 and 00, and the remaining slots are numbered from 1 to 36.

Formula used:

If E is the event in a sample space S, then the probability of E is

P(E)=n(E)n(S)              ...(1)

Calculation:

There are 38 slots in a roulette wheel. So,

n(S)=38

Odd numbers slots in roulette wheel is,

E={1,3,5,
