Question

10. A five-digit access code is used to open the new portion of SWHS. If the first number has to be either a 2 or a 4 and the last number has to be even, how many codes are possible if numbers can be repeated?

Expert Solution

Step 1

The fundamental counting principle is a technique to identify the number of ways multiple independent events can occur. If the first event can be performed in $x_{1}$ ways and the second event can be performed in $x_{2}$ ways then these two events can be performed in $x_{1} x_{2}$ possible ways. This principle gives you the number of outcomes not the probability.
