Apresident and vice president for a sorority are chosen from ten people. how many different president/vice president combinations are possible?

There are 90 ways.

Step-by-step explanation:

We have ten people and we have to chose 2 of those people to be the president and vice president. So first we can chose a president, we have 10 choices for president as there are 10 people.

Now we can chose vice president but this time we only have 9 choices because we already chose a president which gives us 9 other people to chose who the vice president is.

Now we need to multiply 10 and 9 together which gives us the total amount of possible combinations for president and vice president if there are 10 people to chose from.

10*9            multiplying

= 90.

Therefore there are 90 ways for a president and a vice president to be chosen for a sorority from ten people.
