Question

A student considers how mnay people enter a particular bank during the lunch hour and how many exit. She decided to run a simulation. She assigns the value 0 to represent a person entering the bank and 1 to represent a person exciting the bank. Based on a simulation fot the first 20 people she observes, estimate the probability she will see a person entering the bank.

0 1 0 0 0 1 1 1 0 1 0 0 0 1 0 1 0 0 1 0

0.400
0.250
0.500
0.600

Answer 1

0.600

Explanation:

gradpoint

Answer 2

The number of persons entering the bank based on given 20 simulations are 12

The number of persons exiting the bank based on given 20 simulations are 8

We have to find the probability that she will see a person entering the bank.

The probability that she will see a person entering the bank is:

`(12)/(20)`

`0.6`

Therefore, the option 0.600 is correct.
