Question 517043: in a bag there are 11 red buttons,4 green buttons ,1 blue buttons and some yellow buttons the chances of choosing a yellow buttons 1 in 3 how many yellows are there Answer by solver91311(24713) (Show Source):
If the probability of pulling a yellow is 1 in 3, then the probability of not pulling a yellow has to be 2 in 3. There are 16 buttons that are not yellow, so if is the total number of buttons, then
Solve for to get the total number of buttons, then subtract 16 from to get the number of yellow buttons.
