The guide on a tour bus is giving a lecture to the 72 passengers about the historical sites they are passing. the passengers consist of 35 men and women, and the rest are children. if the tour guide chooses one passenger at random go ask a question, what is the probability that the passenger will be a child

There are 72 passengers in total and 35 are men and women as one category.

The number of children are 72 - 35 = 37

So the success is 37 (number of children. And the total number of people is 72.

The probability of a child being asked is 37/72.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
