Students are in a class. 16 are civil engineering (CE) majors, 7 are computer science majors (CS), 10 are business majors (B), 6 are math majors (M), 2 are English majors (E), and 4 are animal science majors (AS). If you randomly select 8 students from the class without replacement and without regard to order, give the number of ways the following events could occur. a) Exactly 4 of the students are CS majors

b) 2 E, 3 CE, 1 AS, 1 M, 1 CS

a) Exactly 4 of the students are CS majors - 2583525

b) 2 E, 3 CE, 1 AS, 1 M, 1 CS - 94080

Step-by-step explanation:

1) In total 8 students need to be selected out of total 45 students

4 need to be selected from CS stream and the other 4 will be selected from the remaining 38 student.

Probability of selecting 4 CS students =

Probability of selecting 4 more students from 38 students

Probability of having exactly 4 of the students from CS majors

*

2) ) 2 E, 3 CE, 1 AS, 1 M, 1 CS

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

if you was gonna solve for a, a is a   < -12
