Question 336942
A bag contains
5 green skittles
3 red skittles
2 orange skittles
6 yellow skittles 
how many green skittles must be added to the bag so that the probability of randomly picking a green skittle is 2/3? explain.
---------------------------------------------
Let the number to add be "x":
(5 + x)/(16 + x) = 2/3
Cross multiply to get:


15+3x = 32 + 2x
x = 17
