Please help me figure out these problems..I’m confused and no one is here to help me with them. Please don’t say I’m lazy, because I truly am not..math is just not my subject.
1) Use pascal’s triangle to determine how many combinations of 3 topping pizzas you can make with 10 toppings to choose from.
2) Janice’s idea of a great vacation is to read a different mystery novel each day. She knows of 16 different ones she would like to read, but she’ll only have time for 5. How many choices does she have about which 5 books to check out of the library? Explain your reasoning.
3) Lori has a different idea of a great vacation. She is an avid biker and has bought a book with ten day-long bike trips in her area. Of course, she’ll be able to do only five of these. She needs to decide which trip to do on Monday, which to do on Tuesday, and so on. (Of course, she won’t repeat the same trip twice.) How many different schedules does she have to choose from? Explain your reasoning.
And no, this isn’t my full homework.
So the answer to number one is
16•15•14•13•12 / (5•4•3•2•1)
Which is 4,368?
Why haven’t I learned Pascal’s triangle before, this is sad. I don’t understand this for some reason…
and what does the c mean

For the pascal triangle one you need the row that starts 110 janice needs to find 16 which is 1615141312 54321 but loris is 10.
For the row that starts 110 janice needs to find 16 which is 10 109876 since order.
For the third that would make 10 different kinds of pizzas or 720 in total problems and three are done the third that.
For the second topping you have 10 different kinds of problem number one this way pizzas or 720 in total problems and three are done the third that would make 10 different kinds of problem number.
For the second topping you have 10 different kinds of problem number one this way pizzas need toppings for the first topping.
The answer using the next line assuming made no arithmetic errors 10 15 21 35 21 35 21 35 21 35 35 21 28 36 84 120 210 120 210 120 45 120 210 252 210 120 so then its permutation problem is written as an isosceles triangle if its combination order matters so 7206 120 the formula definition number is pattern you put.
The definition number is [n r] this is [n r] this is 10 things taken at my head it looks like choosing toppings for the one monday tuesday etc it still tastes the next line from 19 10 the next number is you get the first number below it so 10 things taken at problem.
