16. A box contains 4 right-handed and 6 left-handed screws. Two screws are drawn at random without replacement. Let x be the number of left- handed screws drawn. Find (i) the probability distribution of x, and (ii) expectation of x.

A math class consists of 25 students, 14 female and 11 male. Three students are selected at random to participate in a probability experiment. Compute the probability that three females are selected. Probability of first student being a female = (as a fraction) Probability of second student being a female = (as a fraction) Probability of third student being a female = (as a fraction) Probability that three females are selected = (as a decimal rounded to the nearest thousandth)
