Answer:

0.4 = 40% probability the marble is even numbered given the marble is yellow.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

There are 5 yellow marbles, which means that the number of total outcomes is [tex]T = 5[/tex]

2 of those(2 or 4) are even numbered, which means that the number of desired outcomes is [tex]D = 2[/tex]

Find the probability the marble is even numbered given the marble is yellow.

[tex]p = \frac{D}{T} = \frac{2}{5} = 0.4[/tex]

0.4 = 40% probability the marble is even numbered given the marble is yellow.
