64%
(Right answers only, thanks!)

Answer 1

Explanation:

3 + 3 + 9 + 10 = 25 marbles are contained in the bag.

Picking a yellow marble at random from the bag has a 9/25 chance of happening.

The likelihood of selecting a red, green, or purple marble instead of a yellow marble is:

64% or P(not yellow) = 1 - P(yellow) = 1 - 9/25 = 16/25 = 0.64.

So, 64% is the correct response.
