Answer:
0.57926
Step-by-step explanation:
We have been given that the capacity of an elevator is 15 people or 2385 pounds. The people have weights that are normally distributed with a mean of 165 lb and a standard deviation of 30 lb. We are asked to find the probability that a randomly selected person has a weight greater than 159 pounds.
First of all, we will find z-score corresponding to 159 using z-score formula.
Now, we need to find area under normal distribution curve that is greater than z-score of as:
Using formula , we will get:
Therefore, the probability that if a person is randomly selected, his weight will be greater than 159 pounds, is 0.57926.
Ok so the total number of marbles is 150
And these can be either red, green or blue
If they’re are 9 RM, 15GM and 6 BM then the total number of marbles the student picked was 30M
So 150/30 is 5
So 6 * 5 is 30 so the total number of BM is 30
