Sagot :

Answer:

0.26 or C

Step-by-step explanation:

Basically you would do the sophomores that attended the jazz band concert (35) and divide that by the total number of students. (137) - - 35 ➗ 137 = .2554744526 round that to .26 or 0.26

The probability that a randomly chosen person from this group exists a sophomore and attended the jazz band concert is 0.31.

What is probability?

Probability exists about calculating or estimating how possible or 'probable' something exists to occur.

Let A be the event that a person exists a sophomore.

B be the event that a person attended volleyball game.

A∩B denote the event that a person exists a sophomore and attend volleyball game.

P be the probability of an event.

We have to estimate the value of P(A∩B),

Given: A∩B = 42

P(A∩B) = 42/137 = 0.3065 approximately equal to 0.31

P(A∩B) = 0.31.

The probability that a randomly chosen person from this group exists a sophomore and attended the jazz band concert is 0.31.

Therefore, the correct answer is option D. 0.31.
