In a certain liberal arts college with about 10,000 students, 50% are males. If two students from this college are selected at random, what is the probability that they are of the same gender? Your answer should be rounded to 4 decimal places.

The probability that both the students selected are of the same gender is 0.25.

Step-by-step explanation:

Let X = number of students selected of the same gender.

The probability of selecting a student of a particular gender is,

P (X) = p = 0.50.

The number of students selected is, n = 2.

The random variable follows a Binomial distribution.

The probability of a binomial distribution is computed using the formula:

Compute the probability that both the students selected are of the same gender as follows:

P (Both boys) = P (Both girls) = P (X = 2)

Thus, the probability that both the students selected are of the same gender is 0.25.

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
