Question

250 balls are numbered from 1 to 250 and placed in a box. A ball is picked random. What is a probabilty of picking ball with three- digit number?

Answer 1

150/250 or 3/5 or a 60% chance

Explanation:

Why?

because you need to calculate the number of balls that are a three-digit number and they will not be a three-digit number up until you get to 100 so what is 250-100? its 150 so your fraction is 150/250 or 3/5 if you need it simplified. To get a percent you need to divide 150 by 250 to get 0.6 and then you multiply by 100.
