A crate of soft drinks contains 10 bottles of Coca-cola, 8 of Fanta and 6 of sprite. If one bottle is selected at random, what is the probability that it is NOT a Cocacola bottle?

  • A \(\frac{5}{12}\)
  • B \(\frac{1}{3}\)
  • C \(\frac{3}{4}\)
  • D \(\frac{7}{12}\)

The correct answer is D. \(\frac{7}{12}\)

To find the probability that a randomly selected bottle is NOT a Coca-cola bottle, we need to calculate the ratio of the number of bottles that are not Coca-cola to the total number of bottles.

Total number of bottles = 10 (Coca-cola) + 8 (Fanta) + 6 (Sprite) = 24 bottles

Number of bottles that are not Coca-cola = 8 (Fanta) + 6 (Sprite) = 14 bottles

Probability = \(\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}\)

Probability = \(\frac{\text{Number of bottles that are not Coca-cola}}{\text{Total number of bottles}}\) = \(\frac{14}{24}\)

Simplify the fraction by dividing both the numerator and denominator by their greatest common divisor (2):

Probability = \(\frac{7}{12}\)

So, the probability that a randomly selected bottle is NOT a Coca-cola bottle is \(\frac{7}{12}\).
