A retail shop accepts only cash or checks. Suppose that 57% of its customers carry cash, 50% carry checks, and 39% carry both cash and checks. What is the
probability that a randomly chosen customer at the shop is carrying cash or checks (or both)?
Write your answer as a decimal (not as a percentage).

A retail shop accepts only cash or checks. Suppose that

46

% of its customers carry cash,

37

% carry checks, and

74

% carry cash or checks (or both). What is the probability that a randomly chosen customer at the shop is carrying both cash and checks?

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
