Combine the total number of marbles and that will the denominator.

5 + 4 + 1 = 10

Now the number of white marbles will be the numerator.

[tex]\frac{5}{10}[/tex]

Convert the fraction into a decimal by dividing the top by the bottom.

5 / 10 = 0.5

Now convert the decimal into a percent by moving the decimal point two places to the right and adding % sign.

0.5 = 50%

So, there is a 50% of choosing a white marble.
