Question 1068040
Tickets numbered 1 to 10 are mixed up and then a ticket is drawn at random. What is the probability that the ticket drawn has a number, which is a multiple of 2 or 3? Please help me by showing work, indicating which formula for calculating probabilities were used. 
---------------------
Ans: P(mult of 2) + P(mult of 3) - P(mult of 2 and mult of 3)
-------
= [5 + 3 - 1]/10
-------
= 7/10
