In a statistics class of 13 sophomores, 12 juniors, and 8 seniors, 5 of whom are male sophomores, 6 of whom are female juniors, and 4 of whom are male seniors, what is the probability of randomly selecting a junior or a senior?

Step-by-step explanation:

We are given that

Sophomores=13

Juniors=12

Seniors=8

Male sophomores=5

Female sophomores=6

Male seniors=4

We have to find the probability of randomly selecting a junior or  a senior.

Total persons=13+12+8=33

Let A=Seniors

B=Juniors

Probability,P(E)=

Using the formula of probability

Hence, the probability of selecting a junior or senior=

15 units use socratic

step-by-step explanation: 15 units

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
