If a bag has 6 cards numbered 1 to 6, and 3 of them are purple, the probability of drawing a PURPLE card is:
A1/6
B1/3
C1/2
D3/6 (i.e. 1/2)
Answer & Solution
Correct answer: D. 3/6 (i.e. 1/2)
Favourable outcomes (purple cards) = 3. Total outcomes = 6. Probability = 3/6 = 1/2. Options C and D are equivalent — both are 1/2 (option D shows the working).
