The Blacktop Speedway is a supplier of automotive parts. Included in stock are 8 speedometers that are correctly calibrated and two that are not. Three speedometers are randomly selected without replacement. Let the random variable \( x \) represent the number that are not correctly calibrated.Complete the probability distribution table. (Report probabilities accurate to 4 decimal places.)\[\begin{array}{|c|c|}\hlinex & P(x) \\\hline0 & \\\hline1 & \\\hline2 & \\\hline3 & \\\hline\end{array}\]Find the mean of this probability distribution. (Appropriate rounding rules apply.)Mean = [ ]

We are interested in analyzing data related to college football. Use S to denote the team is in the SEC and use W to denote a team has a winning season. The probability that a team is in the SEC in the data set is 5.5%. The probability that a team has a winning season is 52.5%. The probability that a team is in the SEC and has a winning season is 3.55%. What percentage of teams are in the SEC or had a winning season? b. What percentage of people teams are in the SEC and did NOT have a winning season? Given a team had a winning season, what is the probability that they are in the SEC? а. с.

Recal the example in class and also in the notes I sent to you. Work again on the example as follows. Example: Suppose that 2 defective microwaves have been included in a shipment of 6 microwaves. The buyers want to test the 6 microwaves one at a time. Let Y denote the number of defective microwaves is found after 3 random selected ones have been tested. Find the probability distribution for Y. Y = the number of defective microwaves found after 3 have been tested What's the possible value of Y? Y P(Y=y) ? ? Questions: 1- Fill the table above with random variables and corresponding probabilities? 2- Calculate the probability that the buyers can find at least 1 defective microwave after 3 have been tested? 3- Find the probability that buyers cannot find any defective microwave after 3 random ones have been tested?
