A red card is drawn from a standard deck of 52 playing cards. If the red card is
not replaced, find the probability of drawing a second card that is black.
P(black/red) = 1
(Hint: Half of a standard deck of 52 cards are red cards and the other half are black
cards.)

26/51

Step-by-step explanation:Half of the 52 cards are black, and if you remove the one red card there are only 51 cards left, so the answer is 26 lack cards/52 total cards.

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,
