PLEASE PLEASE PLEASE HELP ME WITH THIS PROBLEM! I HAVE NO IDEA WHAT TO DO!

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

What can each term of the equation be multiplied by to eliminate the fractions before solving? x – + 2x = + x 2 6 10 12

What is the point of inflection for the function f(x)=2cos4x on the interval (0, pi/2)
