Read the following word problem. Give the system of equations AND the solution: Ms. Rubio needs to how many students and adults went to an Edison football game. She knows there were a total of 376 people there (all either adults or students) and she made $2,064 in admission tickets. If student tickets cost $2 and adult tickets are $10. How many students were at the game? How many adults? (you will use these answers for the next slide)
Permutations and Combinations
If there are 5 dishes, they can be relished in any order at a time. In permutation, it should be in a particular order. In combination, the order does not matter. Take 3 letters a, b, and c. The possible ways of pairing any two letters are ab, bc, ac, ba, cb and ca. It is in a particular order. So, this can be called the permutation of a, b, and c. But if the order does not matter then ab is the same as ba. Similarly, bc is the same as cb and ac is the same as ca. Here the list has ab, bc, and ac alone. This can be called the combination of a, b, and c.
