Multiple choice

A marble is drawn at random from a box containing 4 red marbles and 6 white marbles. Column A Column B The probability that the marble is white 2/3 Compare the two quantities to decide whether

  1. the quantity in Column A is greater

  2. the quantity in Column B is greater

  3. the two quantities are equal

  4. the relationship cannot be determined from the information given
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Probability of white marble = 6 / (4+6) = 6/10 = 0.6. Column B is 2/3 = 0.666. Since 0.6 < 0.666, Column B is greater.

AI explanation

The probability of an event is the number of favorable outcomes divided by the total number of outcomes. The total number of marbles is 4 plus 6, which equals 10. The probability of drawing a white marble is 6 divided by 10, which simplifies to 3 divided by 5. Since 3 divided by 5 is 0.6 and the value in Column B is 2 divided by 3 (about 0.67), the quantity in Column B is greater.
