Answer:
a) There is a 55% probability that a person who walks by the store will enter the store.
b) There is a 38% probability that a person who walks into the store will buy something.
c) There is a 21% probability that a person who walks by the store will come in and buy something.
d) There is a 62% probability that a person who comes into the store will buy nothing.
Step-by-step explanation:
This a probability problem.
The probability formula is given by:
In which P is the probability, D is the number of desired outcomes and T is the number of total outcomes.
The problem states that:
121 people walked by the store.
66 people came into the store.
25 bought something in the store.
(a) Estimate the probability that a person who walks by the store will enter the store.
121 people walked by the store, 66 of whom entered the store. So:
There is a 55% probability that a person who walks by the store will enter the store.
(b) Estimate the probability that a person who walks into the store will buy something.
66 people walked into the store, 25 of whom bought something. So:
There is a 38% probability that a person who walks into the store will buy something.
(c) Estimate the probability that a person who walks by the store will come in and buy something.
121 people walked by the store, 25 of whom entered the store. So:
There is a 21% probability that a person who walks by the store will come in and buy something.
(d) Estimate the probability that a person who comes into the store will buy nothing.
Of the 66 people whom came into the store, 25 bought something. This means that 66-25 = 41 of them did not buy anything. So:
There is a 62% probability that a person who comes into the store will buy nothing.
