How many times do you need to pick from a bag to ensure that you have one of each color if there are 7 green 4 blue and 5 red marbles in a bag?

If there were just 7 green and 4 blue involved you would need to pick out at least 8, since this would cover picking out all the greens plus 1 blue. Any choice of less than 8 might produce only greens.
Now in the case where we have 7 green, 4 blue and 5 red marbles we would need to choose 7 + 5 + 1 = 13, since any number less than 13 could be covered by selecting (by chance) all the 7 greens and all the 5 reds with no blue at all.
In this case the answer is found by totalling all numbers other than the smallest, and then adding 1.

What is the chances you will get a blue marble if there is 4 marbles in all?
Depends on the color of the marbles, or more specifically, it depends upon how many of the marbles are blue. If 0 marbles are blue, then the chance is 0. If 1 marble is blue, then the chance is 1/4. If 2 marbles are blue, then the chance is 1/2. If 3 marbles are blue, then the chance is 3/4. If 4 marbles are blue, then the chance is 1. These probabilities assume that you draw only once. The other possibilities are that you draw twice, or three times, or four times. If drawing multiple times, it can be done by putting back each marble after it was drawn, or by keeping it out after it has been drawn.

There are 40 yellow marbles and blue marbles in a bag there are four times as many blue marbles as yellow marbles how many yellow and blue marbles are there?
Set up the problem as: y=number of yellow marbles & 4y=number of blue marbles. 40=y+4y or 40=5y or y=8. Therefore number of blue marbles is 4*8 = 32.
