HELP ON ANY OF THESE WOULD BE GREATLY APPRECIATED

1) In how many different ways can a penny, a nickel, or a dime be given to four children if one of any of the three coins is given to each child?

2) A hypothetical four-sided fair coin is tossed five times. In how many ways will the give tosses not result in all of the same sides of the coin showing up?

3) We want to seat six people, three of each gender, in a row of six chairs. In how many ways can we seat these people if all the men must sit together but no man sits in the first seat or last seat? (When facing the seats, the first seat to the far left)

4) In how many different ways can a group composed of three males and three females be lined up so that no two adjacent people are the same gender?

5) The International Airline Transportation Association (IATA) assigns three-letter codes to represent airport locations. Suppose the code is designed so that the first and last letters have to be the same. How many airport codes would be allowed?


Please help, I have no idea how to do this

We can help - we only help after you have shown your work - or ask a specific question (not a statement like "Don't know any of these")

Please share your work with us indicating exactly where you are stuck - so that we may know where to begin to help you.

I was unaware, thank you. I figured them out on my own.
