Answer 1

Where is the table? we need to see the table first.

Answer 2

Try using the upload file tool to upload the table.

Answer 3

there you go

Answer 4

did you type this all out? is there a cleaner version the the table because this is a bit hard to read...

Answer 5

yes

Answer 6

is this a 2-way table?

Answer 7

the table doesn't match the problem, but I can still walk through the setup

What is the chance of on-time assignment submission if it is a chemistry assignment?

"if it is a chemistry assignment" so it is a given that the assignment is a chemistry assignment. therefore, the denominator of your probability should be the total % of chemistry assignments

"the chance of an on-time assignment submission" so we want the % of on-time chemistry assignments out of all chemistry assignments. simply look at the table, find the % of assignments that are both chemistry *and* on time, and divide by the total % of chemistry assignments
