Question

What is the probability that a roulette ball will come to rest on an even number other than 0 and 00? (Assume that there are 38 equally likely outcomes consisting of the numbers 1-36, 0, and 00. Round your answer to three decimal places.)

Answer 1

0.474

Explanation:

Here we have 38 possible cases because all 38 numbers on a roulette ball have a chance of showing up and those chances are equal.

Also, we have 18 even numbers between 1 and 36 excluding 0 and 00.

Probability is a number of favorable cases divided by the number of possible cases, so, finally, the required probability is:

`P=(18)/(38)=(9)/(19)=0.474`
