Option C: np is the expression used for calculating the mean of a binomial distribution.
Explanation:
From the options, we need to determine the expression that is used for calculating the mean of a binomial distribution.
<u>Option A: npq</u>
The variance of the binomial distribution can be calculated using the expression npq.
Hence, Option A is not the correct answer.
<u>Option B: </u><u></u>
The standard deviation of the binomial distribution can be calculated using the expression
Hence, Option B is not the correct answer.
<u>Option C: np</u>
The mean of the binomial distribution can be calculated using the expression np
Hence, Option C is the correct answer.
<u>Option D</u>:
The mean of the binomial distribution cannot be determined using the expression
Hence, Option D is not the correct answer.
Answer:
15 students
Step-by-step explanation:
First, change the fraction to a decimal: 6/10 = 0.6
Next, multiply 25 with 0.6: 25 x 0.6 = 15
15 students is your answer
