Erma maintains an active blog about her seashell collection. She has 500 white shells, 325 yellow shells, 115 pink shells, and 6
0 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%
Answer: B. <span>White: 50% Pink: 11% yellow: 32.5% green: 6% </span>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%
The answer is B. White 50%: Pink 11%: Yellow 32.5%: Green: 6%
If you add the number of seashells Erma has in total, it would sum up to 1000. The probability that you will pick a certain color out of all the seashells is: ((Number of seashells of a certain color)/(Total number of seashells))*100%=The probability that that color will be picked.
21/2 is 10.5 so that would be the length of the diagonal near the 4 and the side would be 4 which 10.5 is the lengths of the other 2 diagonals so you take LxW
