Students at University X must be in one of the class ranks—freshman, sophomore, junior, or senior. At University X, 35% of the students are freshmen and 30% are sophomores. If a student is selected at random, the probability that her or she is either a junior or a senior is

Percentage of probability of junior or senior student is 35%.

Step-by-step explanation:

Given:

Freshmen = 35%

Sophomores = 30%

We need to find the the probability of student either a junior or a senior.

Solution:

From the above statement there are four classes, where freshmen is 35% and

sophomores is 30%,

So the probability of freshmen and sophomores as.

The probability of junior or senior student is one minus the probability that event does not occur.

Therefore, the probability of student either a junior or a senior is 0.35 or percentage of probability is 35%.

50=33x+22

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
