Question

Seventy-five balls numbered from 1 to 75 are placed in an urn. One ball is randomly drawn from the urn. What is the probability that the number on the ball is greater than or equal to 32?

Answer 1

75-31= 44
44/75= 0.58666 or 58.7%

Subtract 31 from 75 since we're figuring out greater than or "equal to" we want to include the number 32 in our equation. If it was only "greater than" 32 then we'd subtract 32 from 75. Then you divide that number(44) by 75, which is all the possible outcomes you could have in this scenario. Move the decimal two places to the right to make it a percentage and you've got your answer.
