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: 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 :)
