Abag contains 5 yellow marbles, 7 pink marbles, and 3 purple marbles. gordon selects a marble without looking. what is the probability that he selects a yellow marble or a purple marble? a. b. c. d.

The probability that he selects a yellow marble or a purple marble is:

  8/15

Step-by-step explanation:

We are given that:

A bag contains 5 yellow marbles, 7 pink marbles, and 3 purple marbles.

Gordon selects a marble without looking.

we have to find  the probability that he selects a yellow marble or a purple marble

P(yellow marble or purple marble)= number of yellow or purple marbles/ no. of marbles

                                          = (5+3)/(5+7+3)

                                          = 8/15

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

the answer is b.)
