Question

A jar contains 17 orange, 7 pink, and 4 black marbles. A marble is drawn at random. What is the probability that the marble is pink or orange?

Answer 1

If you are finding the probability of the marbles being drawn that are pink are orange you first find the total: 28. Then you find the the amount of marbles that are either pink or orange; in this case its 17. Finally you take the amount of pink and orange marbles and divde it by the total amount

17+7+4= 28

Pink or orange marbles
17+7= 24

Probability
28/28=.857

or 86% chance that a marble being drawn is pink or orange

Answer 2

17+7+4=28

17+7=24

24 out of 28
