Question

18.

There are 100 cards, numbered 1 to 100, face down on a table.
What is the probability that Jenny picks a card with a number less than 81?
Write your answer as a fraction in its simplest form.

Answer 1

19/100 which is already simplified( it can't be simplified)

How I got the answer: subtract 81 from 100 and you'll get 19.

Put 19 over 100 (19/100) and there's the answer.
