In this case, we'll have to carry out several steps to find the solution.
Step 01:
data:
red marbles = 10
blue marbles = 23
Step 02:
probability:
probability (event) = favorable outcomes / total outcomes
1. probability (red marble):
[tex]p=\frac{10}{23+10}=\frac{10}{33}=0.30303[/tex]2. probability (red marble):
[tex]p=\frac{9}{23+9}=\frac{9}{32}=0.28125[/tex]total probability:
[tex]p=0.30303*0.28125=0.0852=0.09[/tex]The answer is:
p = 0.09
