WILL MARK BEST ANSWER BRAINLIEST; WORTH 15 POINTS A bag contains equal-sized disks that are either red, green, yellow, or blue. There are 6 red disks, 3 green disks, 6 yellow disks, and 5 blue disks. If a disk is selected at random from the bag, what is the probability that the disk will be either red or yellow?

3/5

Step-by-step explanation:

There are 20 discs in total. We need to find the probability of picking out either a red or yellow disc. There are 6 red discs and 6 yellow discs, a total of 12. This means that our chances of picking out a red or yellow disc from the bag is 12/20, which can be simplified to 3/5.

3/5 or 60%

Step-by-step explanation:

Total disks: 6+3+6+5= 20

red+yellow disks: 6+6=12

red+yellow/total disks=12/20

FRACTION:

simplify: 12/20=6/10=3/5

3/5 probability of a red or yellow disk

PERCENTAGE:

12/20=60/100

60% chance of red or yellow

2/5

step-by-step explanation:

a = 11 : 4

b = 38

c = 1 for every 6
