) Of the Statistics graduates of a University 35%, received a starting salary of $40,000.00. If 5 of them are randomly selected, find the probability that all the graduated had starting salary of $40,000.00.

The probability that all the graduated had starting salary of $40,000.00 is 0.00525.

Step-by-step explanation:

We are given that at of the Statistics graduates of a University 35%, received a starting salary of $40,000.00.

Also, 5 of them are randomly selected.

The above situation can be represented through Binomial distribution;

where, n = number of trials (samples) taken = 5 graduates

            r = number of success = all 5 had starting salary of $40,000

           p = probability of success which in our question is % of Statistics

                 graduates who received a starting salary of $40,000, i.e; 35%

LET X = Number of graduates who received a starting salary of $40,000.00

So, it means X ~ Binom(n = 5, p = 0.35)

Now, Probability that all the graduated had starting salary of $40,000.00 is given by = P(X = 5)

                   P(X = 5)  =  

                                  =  

                                  =  0.00525

Hence, the probability that all the graduated had starting salary of $40,000.00 is 0.00525.

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
