I'm assuming your question is the probabilty of picking one marble and it being white, pink, or green
Because you have a total 71 marbles, then the probability you pick a white marble is 19/71, a pink marble is 6/71, and probabilty of getting a green is 25/71
To find the probabilty of getting any of the 3 colors, add their probabilties
19/71 + 6/71 + 25/71 = 50/71
Your other choice is to find the probabilty of NOT getting one of those 3 colors, meaning you picked an orange
the probability of getting an orange is 21/71
The subtract 21/71 from 71/71 to find the probability of one of the other 3.
