A 6-cylinder engine has two defective spark plugs. Three spark plugs were selected randomly and their condition was examined. Considering that X is a number of spark plugs that are not working properly, find: a. The probability distribution of X and express it in a table form
b. The expected value of X
c. The standard deviation
d. The probability that at least two spark plugs not working properly.

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
