Multiple of 2 and 7 will be multiple of 14, out of 100, there are 7 multiples of 14, hence probability of randomly choosing a number that is multiple of 2 and 7 will be 7/100=0.07
There are 50 multiples of 2 and 14 multiples of 7 in the first 100 positive integers. This has to exclude the repeated numbers which are both multiples of 2 and 7. Hence out of 100, there are 64-7=57 unique occurrence of numbers that are multiples of 2 or 7, hence probability of choosing a number that is multiples of 2 or 7 is 57/100=0.57
