25% of the 200 jelly beans are green, by converting 25% into a decimal and multiplying it by the total amount of jelly beans, you can find the amount of jelly beans that are green.
25% = 0.25
200 x 0.25 = 50
Therefore 50 of the jelly beans are green.
The question wants to know the probability of the jelly bean being picked is not green.
