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?

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
