John runs a computer software store. Yesterday he counted 121 people who walked by the store, 66 of whom came into the store. Of
Dominik [7]

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:

P = \frac{D}{T}

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:

D = 66, T = 121

P = \frac{D}{T} = \frac{66}{121} = 0.55

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:

D = 25, T = 66

P = \frac{D}{T} = \frac{25}{66} = 0.38

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:

D = 25, T = 121

P = \frac{D}{T} = \frac{25}{121} = 0.21

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:

D = 41, T = 66

P = \frac{D}{T} = \frac{41}{66} = 0.62

There is a 62% probability that a person who comes into the store will buy nothing.
