Answer:

0.474

Step-by-step 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:

[tex]P=\frac{18}{38}=\frac{9}{19}=0.474[/tex]
