I need someone to helpe me explain 3b, 3c, and 3d more clearly for the code for MATLAB. What is the correct way of coding these problems on MATLAB, ive tried different attempts and each attempt i get a different answer. Thank you can someone show me the code

3. a. b. Here are some discrete math questions for you to implement in MATLAB. If you have four people, how many different ways can you arrange them in a line? How many different robotics teams of 7 members can you form from a class of 28 students? (Combinations-order does not matter) Since each player on a robotics team is assigned a particular role, order does matter. Recalculate the possible number of different robotics teams that can be formed when order is taken into account. There are 52 different cards in a deck. How many different hands of 5 cards each are possible? Remember, every hand can be arranged 120 (5!) different ways. What are the chances of getting dealt a royal flush? C. d
