a. what is the probability that the tile will NOT be green?


b. what is the probability the tile is yellow or red?

Answer :

Answer:

a. 17 in 23, 17/23

b. 12 in 23, 12/23

Step-by-step explanation:

for a-

5+6+9+3=23

23 tiles, and 6 are green, 17 are different colors, so

you have a 17 in 23 chance of getting a tile that is not green. (this can also be written as 17/23)

for b-

5+6+9+3=23

23 tiles, and 3 are red, 9 yellow  so

you have a 12 in 23 chance of picking a red or yellow tile,  (this can also be written as 12/23)
