What is the probability that the first two would not recommend their attorney and the third is not sure if he or she would recommend their attorney?

Question

A sample of 38 people who recently hired an attorney yielded the following about their attorneys.

 

numbers of ppl  would recommend 

24                              Yes 

9                               no 

5.                              Not sure

 

 

th people who provided information for the table were selected at random. 

Answer 1

The probability of one not recommending is 9/38

The probability of 2 not recommending is 9/38 x 9/38 or 9/38^{2  =}  .056

Now the probability of one person "not sure" is 5/38 or .13

The probability that 2 don't recommend and 1 isn't sure is .056 x .13  = .00728 or 7/1000 or to be exact 728/100,000
