Erma maintains an active blog about her seashell collection. she has 500 white shells, 325 yellow shells, 115 pink shells, and 60 green shells in her jar. she asks sweet t to reach into her jar and randomly selects a shell. then she replaces it and shakes up the jar before asking sweet t to pick another shell. which model shows the probability of a randomly selecting each color shell from her jar? a. white 60% pink: 10% yellow: 20% green: 10% b. white: 50% pink: 11% yellow: 32.5% green: 6% c. white: 25% pink: 25% yellow: 25% green: 25% d. white: 100% pink: 23% yellow: 65% green: 12%

B. White: 50% Pink: 11% yellow: 32.5% green: 6%
I believe there is a small typo here, as the probability of pink should be 11.5%
based on the calculations below.

Explanation:
probability of each color=number of shells of this color/total number of shells
To get it in percentage form, we will then multiply the probability by 100

We have:
number of white shells = 500 shells
number of pink shells = 115 shells
number of yellow shells = 325 shells
number of green shells = 60 shells
total number of shells = 500 + 115 + 325 + 60 = 1000 shells

Now, we will get the probability of each color as follows:
probability of white shells = (500/1000) * 100 = 50%
probability of pink shells = (115/1000) * 100 = 11.5%
probability of yellow shells = (325/1000) * 100 = 32.5%
probability of green shells = (60/1000) * 100 = 6%

Hope this helps :)
