Asked by Shelly

A box contains different coloured counters. The probabilities of randomly selected a particular type of counter are as follows: Purple = 1/10, Yellow = 1/5, Orange = 3/5

Are there any other coloured counters beside Purple, Yellow and Orange in the box?

Calculate the probability of selecting the other colour
Answered by Reiny
Yes, since 1/10 + 1/5 + 3/5 = 9/10 which is not equal to 1

so the prob of selecting the other colour(s), there could be more than one other, is 1/10
