A math class consists of 21 female students and 16 male students. Two students are selected at random to participate in a probability experiment. Compute the following probabilities. Write your answers in decimal form. Round to the nearest thousandth as needed. a. A male is selected, then a female.

b. A female is selected, then a male.

c. Two males are selected.

d. Two females are selected.

e. No males are selected.

Which simplifys to a+ b? a-(1-b)+1 -(1-a)-b+1 (a--1) -1)+1

How can you find the mean absolute deviation (mad) for this set of data?
