Question

Five hundred draws are made at random with replacement from a box of numbered tickets; 276 are positive. Someone tells you that 50% of the tickets in the box show positive numbers. Do you believe it

Answer 1

Answer: No

Explanation:

Based on the information given in the question, I don't believe that 50% of the tickets in the box show positive numbers.

Since 500 draws are made and 276 are positive, the percentage of the tickets that'll show positive numbers will be:

= 276/500 × 100

= 55.2%

Therefore, about 55.2% of the tickets are positive. The statement that 50% are positive is incorrect.
