Ajar contains a mixture of 20 black marbles, 16 red marbles, and 4 white marbles, all the same size. find the probability of drawing a white or red marble on the first draw.

Step-by-step explanation:

Given: The number of black marbles in jar = 20

The number of red marbles in jar = 16

The number of white marbles in jar = 4

The total number of marbles in jar =

The probability of drawing white marble =

The probability of drawing red marble =

Now, the probability of drawing a white or red marble on the first drawis given by :

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
