Probability of multiples

vendredi 27 juin 2014

1. The problem statement, all variables and given/known data

An integer is chosen random from the first 100 positive integers. What is the probability that the integer is divisible by 6 or 8?





2. Relevant equations

NaN





3. The attempt at a solution

The answer is 24/100 if I ignore one of the Multiples of 6 AND 8,which occurs 4 times in 100

The answer is 28/100 if I include the numbers which occur twice



What is correct here?
