10 + 3 + 7 + 5 = 25 total number of marbles.

10/25 red marble x 3/24 blue marble x 7/23 white marble x 5/22 green marble =1,050/303,600 =0.0034585 x 100 =o.34585% - probability of  picking one of each colors on the first try.

Hi guest,

You have chosen them in the order red blue white green. but they can be chosen in any order 

So I think you answer should be multiplied by  4!
