Suppose that 5 cards are drawn from a well-shuffled deck of 52 cards. what is the probability that all 5 are hearts ?

Simplify (a/b - b/a) times (a - a^2/a+b) a - a^2/a=b is a mixed number

Ineed if you could explain and give me the answer you! this needs done

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
