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.
