Answer 1

How would you begin this excercise?

Answer 2

I have tried doing the 78!
where 78 x 77 x 76 x 75 x 74 = 2,533,330,800 it is incorrect

Answer 3

Why would it be incorrect? If it doesn't matter if it's one of the Senate or one of the House, it should be correct

Answer 4

it says it is incorrect. that is the most logical way i find to answer the problem. Do you have any other ways? i am stuck on this one.

Answer 5

let me break it down. first we add 27 + 51 = 78
78 members in total
then is asks me how many ways are there to choose a group of five members from the PR Legislature

Answer 6

78!/5!(73!)
the answer is 21,111,090

Answer 7

I'm sorry I couldn't help

Answer 8
