Okay, I just want to make sure I'm doing this correctly. Would I put 80 over the total (400) and multiply that by 2?

oh, okay. thanks XD

bloomlocke367 · Answer

80/400=1/5. 1/5*2=2/5

bloomlocke367 · Answer

that's not an option... what did I do wrong?

rational · Answer

the probability is just about drawing a blazers student in the "second try"

bloomlocke367 · Answer

ohhh, so it's just 1/5?

rational · Answer

in the second try also
80 blazers students
and 400 total students

so the probability is simply 80/400

rational · Answer

Yes!

bloomlocke367 · Answer

wait, but it asked the prob the principal will draw ANOTHER student...

bloomlocke367 · Answer

in that, wouldn't there be the possibility that the same student would be drawn?

rational · Answer

yes "another blazers student"
he can be same as the previous one
