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

Naily [24]

Answer: 1406

Step-by-step explanation:

Given Table :

Admissions Probability

1,040 0.3

1,320 0.2

1,660 0.5

Now, the expected number of admissions for the fall semester is given by :-

$E(x)=p_1x_1+p_2x_2+p_3x_3\\\\\Rightarrow\ E(x)=0.3\times1040+0.2\times1320+0.5\times1660\\\\\Rightarrow\ E(x)=1406$

Hence, the expected number of admissions for the fall semester = 1406
