The grams of sugar per serving for three brands of cereal are 4 g, 10 g, and 14 g. The probability of choosing a cereal with 4 grams of sugar is 1/4 . The probability of choosing a cereal with 10 grams of sugar is 5/8 . The probability of choosing a cereal with 14 grams of sugar is 1/8 . What is the expected value of the number of grams of sugar in cereal?

Step-by-step explanation:

Given

Cereal A

Cereal B

Cereal C

Required

Determine the expected value of grams of sugar

This is calculated by multiplying the probability and grams of sugar in each cereal.

The results of the products are then added together

i.e.

Hence;

The expected value of grams of sugar is 9 grams

based on context clues you gave i'm assuming the answer would be c.

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
