Question

A bag contains 6 blue marbles, 2 red

marbles, 4 yellow marbles, and 8 green
marbles. What is the probability of drawing
a red marble at random from the bag?

Answer 1

Answer:
Here we have to use combination because the marble is chosen at random.
Probability = x/total
x= 2C1 =2
Total= 20C1 =20
Probability = 2/20 = 1/10
HOPE THIS HELPS :)

Answer 2

It would be 2/20 or if you want the simplified version, it’s 1/10.
