Choose the one alternative that best completes the statement or answers the question. A shipment of twenty radios contains six defective radios. Two radios are randomly selected from the shipment. 14) Find the probability that both radios selected are defective

Step-by-step explanation:

Here, the total number of radios  = 20

The number of defective radios  = 6

The number of radios selected at random = 2

P(Selecting first defective radio)  =

Now, after selecting first defective radio, total radios left = 20 - 1 = 19

Also, total defective radios  = 6 - 1 = 5

P(Selecting second defective radio)  =

So, the combined probability of selecting 2 defective radios

Hence, the probability that both radios are defective  =

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
