Choosing a number from 1 - 400 |
2008-07-04 |
|
Peter pose la question :
The numbers 1-400, inclusive, are put into a hat. What is the probability that the first number chosen at random is a multiple of 4 or 17? Express your answer as a common fraction.
How do you do this the question without a calculator?
