Part A: About 0.21
We will put the wanted outcome (yellow pieces of candy) over the total number of possible outcomes (total pieces of candy).
[tex]\frac{5}{3+6+5+2+8}[/tex]
[tex]\frac{5}{24}[/tex]
About 0.21
Part B: About 50
First we will do the same as we did with the yellow pieces of candy, wanted outcomes over possible outcomes.
[tex]\frac{6}{3+6+5+2+8}[/tex]
[tex]\frac{6}{24}[/tex]
0.25
Now, we will multiply the total 200 pieces by 0.25 since 0.25 of them are estimated to be green.
200 * 0.25 = 50
I estimate about 50 of the pieces to be green.
