4x = 12

x = 12/4

x = 3 <=======

3y = 24 - 3

3y = 21

y = 21/3

y = 7 <========

Choose whether the probability is mutually exclusive or not

Semmy [17]

Answer:

mutually exclusive

Step-by-step explanation:

The formula of interest is ...

P(A or B) = P(A) + P(B) - P(A and B)

Filling in the given values, we have ...

9/10 = 2/5 + 1/2 - P(A and B)

Solving for P(A and B), we get ...

P(A and B) = 2/5 +1/2 -9/10 = 4/10 +5/10 -9/10

P(A and B) = 0

__

Events are mutually exclusive when <em>they can never happen at the same time</em>. That is, P(A and B) = 0.

The events A and B are mutually exclusive.
