Uisng the principle of probability, the number of purple marbles in the bag is 96

Given the Parameters :

  • Theoretical probability = 4/5
  • Number of marbles = 120

Number of purple marbles can be calculated thus :

Probability × total number of marbles

(4/5) × 120

0.8 × 120 = 96 marbles

Hence, number of purple marbles is 96.
