Question

Hi everyone! I got another problem I need help on over probability. No links or you will be reported!!!

Please help me solve this. Where I'm going wrong and an explanation would be very helpful as well.

problem: The data in the following table shows the outcomes of guilty and not-gulity pleas in 1055 criminal court cases.

Sent to prison:
Guilty plea: 399
Not-gulity plea: 59

Not sent to prison:

Guilty plea: 567
Not-gulity plea: 29

A. What is the probability that a randomly selected defendant either pled guilty or was not sent to prison? (round to three decimal places as needed.)

​

Answer 1

0.944

Explanation:

First of all, are you sure the datas are alright? We have a count of 1054 defendants while adding up all these numbers.

Assuming the datas are true, out of the 1054 defendants:

- 399 are sent to prison and guilty

- 567+29 = 596 aren't sent to prison.

Since we are looking for the probability that a randomly selected defendant either pled guilty or was not sent in prison, it means we have

`(399+596)/(1054) = (995)/(1054) = 0.944`

(rounded to three decimal places).
