Kaleb is not doing too well in Mario Kart. However, he can still get 1st for the circuit. He knows getting 1st place in a race earns him 15 points and coming in 2nd earns him 12 points. Kaleb needs to earn more than 30 points to beat Wario and get 1st for the circuit. Write an inequality that describes the situation.

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
