Using the binomial distribution, it is found that the number of students that would be expected to select a gold-wrapped candy from the bag is given by:
The candies are chosen with replacement, which means that for each student, the probability of choosing a gold wrapped candy is independent of any other student, hence the binomial distribution is used.
<h3>What is the binomial distribution?</h3>
- The <em>binomial distribution</em> is the <u>probability of exactly x successes on n repeated trials, with p probability of a success on each trial</u>.
The expected value of the binomial distribution is:
In this problem:
- There are 15 students, hence .
- Of a totlal of 5 + 1 + 2 + 4 = 12 candies, 4 are gold wrapped, hence
Then, the <em>expected value</em> is:
Hence, option B is correct.

Answer:
12
40
48
7
Step-by-step explanation:
To solve the equation use inverse operations. When multiplication is present, use division. When division is present, use the reciprocal and multiplication.
3/4 x= 9 x = 9 * 4/3 = 12
5/8 k= 25 x = 25 * 8/5 = 40
a/6 = 8 x = 8*6 = 48
7s = 49 s = 49/7 = 7
