The probability is 100%.There's no way to take four marbles out of this bag without at least one of them being white.

Probability of drawing a red marble = 4/16 = 1/4 Probability of drawing not a red marble = 1 - 1/4 = 3/4
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17

The theoretical probability of randomly picking each color marble is the number of color marbles you have for each color, divided by the total number of marbles. For example, the probability of selecting a red marble is 3/20.
None, if all the marbles that you have are yellow!
probability of pulling out a purple marble = 20/85probability of NOT pulling out a purple marble = 1 - 20/85 = 65/85 = 13/17
7/15 for blue marbles and 8/14 for the purple marbles this is dependent probability
it depends how many blue marbles there are and how many marbles total.
