Thirty people attend an event in which 5 are chosen at random to receive door prizes. the prizes are all the same, so the order in which the people are chosen does not matter. how many different groups of five people can be chosen?

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
