How many possible outcomes are there? Well that would be ALL the marbles...so 3 + 2 = 5

Out of those 5 possible outcomes...we want to pick a white marble...there are 2 of those...

So our probability would be

$$\large \frac{\text{Outcomes we want}}{\text{Possible outcomes}} = \frac{2}{5} = \space ?$$
