Answer:

15i

Step-by-step explanation:

(-2+i)(3-6i)

Use the FOIL method then combine the real and imaginary parts of the expression.

(-2+i)(3-6i)

-2 (-3-6i) + i (3-6i)

-2 * 3 - 2 (-6i) + i (3-6i)

-2 * 3 - 2 (-6i) + i * 3 + i (-6i)

-6 + 12i + 3i + 6

0 + 12i + 3i

12i + 3i

15i

IceJOKER [234]

Let Ch and C denote the events of a student receiving an A in chemistry or calculus, respectively. We're given that

P(Ch) = 88/520

P(C) = 76/520

P(Ch and C) = 31/520

and we want to find P(Ch or C).

Using the inclusion/exclusion principle, we have

P(Ch or C) = P(Ch) + P(C) - P(Ch and C)

P(Ch or C) = 88/520 + 76/520 - 31/520

P(Ch or C) = 133/520
