Answer:

15 times

Step-by-step explanation:

Probability is calculated as

probability = \frac{favourableoutcomes}{count}

Here a favourable outcome is an even number : 2, 4, 6 and the count is 6

P(even number) = \frac{3}{6} = \frac{1}{2}

expected even number = \frac{1}{2} × 30 = 15 times

The director of admissions at Kinzua University in Nova Scotia estimated the distribution of student admissions for the fall sem
svlad2 [7]

Answer:

The expected number of admissions for the fall semester is approximately 1248 students.

Step-by-step explanation:

We are given the following information in the question:

Number of Students:      1,060         1,400        1,540

               Probability:       0.61           0.11            0.3

Formula:

\text{Expectation} = E(x) = \sum xP(x)

Expected number of admissions for the fall semester =

E(x) = \sum xP(x)\\= (1060\times 0.61) + (1400\times 0.1) + (1540\times 0.3)\\=1248.6

Hence, the expected number of admissions for the fall semester is approximately 1,248 students.
