Answer 1

For a set of trials
`P_(desired)=(desired)/(total)`. In this case our desired out come is all multiples of 3: 3,6,9 and 12. The total number of outcomes can be found as 100 by adding up all the frequencies. Thus our experimental probability is
`P_(x=3n)=(6+14+12+1)/(100)=(33)/(100)=33\%`.
