Answer:

So for the table , .3 + .1 + .25 + .35= 1.

and 10 green pins. read my explanation please cause i worked a lot on this.

Explanation:

So first we add the probability of purple and gray getting picked.

.35 + .25= .6

And we know that the probability of green is 3 times yellow.

So. yellow can be x. and the equation would look like this.

3x + x +.6= 1

x equals .1, because 3x + x or 3(.1) + .1= .4

So, .3 + .1 + .25 + .35= 1.

This should be enough info to complete the table. Now b.)

So we know 14 purple pins... and the probability of that is .35

so if 14 = .35 what equals .25?

(I'm going to convert these decimals into percents for problem b until we get the answer, and then i'll make it back to a decimal form)

Okay, so

14= 35%

and that means .4 equals 1% or .01 probability

so now we times .4 to 25% to find out how many green pins are there.

.4 * 25= 10

So there are 10 green pins.
