2. what is the probability of selling between and including one and four silver cars? interpret this probability in context.

0.72868

Problem Statement:

23% of the cars a certain automaker manufactures are silver. Below is the probability distribution for the number of

silver cars sold by a car dealer in the next five car sales.

No. of  Silver Cars    0             1             2              3              4             5

Probability         0.27068   0.40426  0.24151  0.07214  0.01077  0.00064

Step-by-step explanation:

To find the probability that the dealer sells between one and four silver cars, we need to add the probabilities of him selling 1,2,3 or 4 cars.

Probability that the dealer sells between and including one and four silver cars= 0.27068+ 0.40426  + 0.24151  + 0.07214  =0.72868

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
