# Question: One of the most profitable items at A1 s Auto Security

One of the most profitable items at A1’s Auto Security Shop is the remote starting system. Let x be the number of such systems installed on a given day at this shop. The following table lists the frequency distribution of x for the past 80 days.

a. Construct a probability distribution table for the number of remote starting systems installed on a given day. Draw a graph of the probability distribution.

b. Are the probabilities listed in the table of part a exact or approximate probabilities of various outcomes? Explain.

c. Find the following probabilities.

i. P(x = 3)

ii. P(x < 3)

iii. P(2 < x < 4)

iv. P(x < 4)
