Question

A matchbox contains 10 matches, but 3 have already been used. If you pick 2 matches at random from the box, what is the probability that neither of those matches would have been used?

Answer 1

Answer:

14/20

Step-by-step explanation:

Probability of picking one match and getting a non used match = 10-3/10=7/10

Therefore,Probability of picking two matches and getting a non used match=7/10 X 2/2= 14/20
