The probability that the major of one student that is selected at random is engineering can be calculated by the total number of engineering major divided by the total number of students
p = engineering / total students
p = 300 / ( 300 + 700 + 500)
p = 0.2 is the probability of the major of one student is engineering
K = 70 i did 6 x -5 which was -30 then -30+100 = 70

(20 / 2^2 * 5 / 5) = 5
Multiplication
5*8= 40
Division
10 / 40 = 0.25
Subtraction
0.25 - 2 = −1.75
Therefore,
The answer is -1.75
