Answer:

C. 0.12

Step-by-step explanation:

<u>Independent events</u>

The outcome of one event does not affect the outcome of the other. If A and B are independent events then the probability of both ocurring is:

P(A and B) = P(A) x P(B)

With P(A) = 0.40 and P(B) = 0.30 then

P(A and B) = 0.40 x 0.30 = 0.12

Discussion

I can sympathize with your confusion. You might be helped if you knew what the squares meant. Is 1 square = 1 inch or 4 miles? You don't know and can't tell. So I'm going to say that 1 square is 1 unit.

The vertical line is 3 units long.

The horizontal line is 4 units long.

Formula

Area = 1/2 horizontal * vertical or

Area = 1/2 * base * height Substitute givens into this formula

Substitution and Solution

Area = (1/2) 3*4

Area = (1/2) 12

Answer: Area = 6 units
