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%.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
