The fountain contains 20 pennies and 9 dimes. a coin is randomly taken and not replaced. a second coin is randomly taken. what is the probability that both coins are pennies?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18

B. two events are dependent if the occurrence of one event changes to occurrence of the second event. true or false

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
