I have questions like
they're are n beads in a jar
5 beads picked were black
A sample of 50 beads were taken from the jar.
40 beads were black.
So I do 50 * 40 / 5 = 400 beads in total
I need similar questions made by you guys to help me revise for my maths exam which is in two days.
Can you write questions which are similar then press enter a few times and write the answer, that way I can check if I'm doing it correct.
Any help will be appreciated!
