About this worksheet

How likely? Chances from 0 to 1. Every version has 10 questions, and the answer key prints on the second page.

What your child will learn

  • I can say how likely something is from its chance: near 0 is unlikely, about 1/2 is about as likely as not, near 1 is likely.
  • I can compare two chances, even when one is a fraction, one a decimal and one a percent, and say which is more likely.
  • I can find the chance that something does NOT happen: 1 minus the chance that it does.

Standard: 7.SP.C.5

Words to know

chance (probability): How likely something is, as a number from 0 to 1.

impossible, certain: Impossible has a chance of 0. Certain has a chance of 1.

unlikely, likely: Unlikely is a chance close to 0. Likely is a chance close to 1.

about as likely as not: A chance of about 1/2: as many rows count as do not.

event: The outcomes the question asks about, like "a star".

NOT (complement): Everything that is not the event. Its chance is 1 minus the event's chance.

Your child compared the outcomes that count with the ones that don't instead of with all of them.
