Michael, Jonathan and two of their friends each ride their bikes to school. If they have an equally-likely chance of arriving first, what is the probability that Jonathan will arrive first and Michael will arrive second?

There are four friends right? So the probability for Jonathan to arrive is 1/4. And the probability for Michael to arrive is 1/4. So you multiply since it deals with 'and' the answer would be. 25x. 25 =.0625 in decimal form and in fraction form is 1/16
