5/6 or 83% (roughly, since probability is never exact).
(hope this helps!)
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
X=1/3 or x=-2
explanation:
Find factors of 3 and 2 which subtract to make 5.
We should realise that (3x2) - 1 = 5.
Find the cross products and subtract to get 5. Add in the signs. One of the factors must be 0.
