Roberto has a bag that contains 7 blue, 5 purple, 12 red, and 6 orange marbles. If he draws one marble at random from the bag, what is the probability of selecting a RED or ORANGE marble?

Respuesta :

Answer:

60%

Step-by-step explanation:

There are 7 blue, 5 purple, 12 red, and 6 orange marbles.

There are 30 marbles in all.

There are 18 red and orange marbles. There are 18 preferred events and 30 total events.

[tex]\frac{preferred}{total} =\frac{18}{30} =\frac{6}{10}=0.6 = 60[/tex]%

There should be 60% chance that Roberto would pick either a red or orange marble.

I'm giving you 3 different answers because I don't know if you need it as a fraction, decimal, or percent

7 + 5 + 12 + 6 = 30

12 + 6 = 18

18/30

simplify

18 / 2 = 9

30 / 2 = 15

9/15

change to a decimal

9 / 15 = .6

change to a percent

.6 x 100 = 60%
