Sagot :
Polly and Percy were sharing a bag of jelly beans.
The bag contains the following number of jelly beans.
Orange = 52
Lime = 63
Cherry = 72
Lemon = 28
Grape = 65
If poly pulls out the first jelly bean what is the probability that that jelly bean is lemon?
Recall that the probability of an event is given by
[tex]P=\frac{number\: of\: favorable\: outcomes}{total\: number\: of\: outcomes}[/tex]For the given case, the favorable outcome is selecting a lemon jelly bean.
Number of lemon jelly beans = 28
Whereas the total number of outcomes is
Total number of jelly beans = 52 + 63 + 72 + 28 + 65 = 280
So, the probability of selecting a lemon jelly bean is
[tex]\begin{gathered} P(lemon)=\frac{number\: of\: lemon\: jelly\: beans}{total\: number\: of\: jelly\: beans} \\ P(lemon)=\frac{28}{280} \\ P(lemon)=\frac{1}{10} \\ P(lemon)=0.10 \end{gathered}[/tex]Therefore, the probability that that jelly bean is a lemon is 1/10
