Question

Suppose 10% of all redeemed coupons at a supermarket are for 50% off the item purchased.

A simulation is used to model a coupon randomly selected and then recorded as 50% off or not 50% off.

Which simulation best models the scenario?




Place 40 equally sized pieces of paper in a hat. Of the 40, 4 read “50% off” and the rest read “not 50% off ”.


Place 80 equally sized pieces of paper in a hat. Of the 80, 10 read “50% off” and the rest read “not 50% off ”.


Place 50 equally sized pieces of paper in a hat. Of the 50, 10 read “50% off” and the rest read “not 50% off ”.


Place 30 equally sized pieces of paper in a hat. Of the 30, 6 read “50% off” and the rest read “not 50% off ”.

Answer 1

I believe it's the first one, I divided 40 by 4 and it gave me 10, but i could easily be wrong.

Answer 2
