Question

A box contains 3 blue, 2 white, and 5 red marbles. If a marble is drawn at random from the box, then what is the probability that the marble will be any one colour?​

Answer 1

Answer:

1/10

Total number of marbles = 3 blue + 2 white + 5 red

= 10

If one is drawn at random the probability of it being on any one colour is = 1/total number of marbles

=1/10

I hope that helps.
