A school fair sells 60 scratch cards, of which 15 carry a prize and the other 45 carry nothing. One card is picked at random. What is the probability that the card carries no prize?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → \(\frac{3}{4}\)
Each of the 60 cards is equally likely to be picked, and a card that carries no prize is one of the 45 cards with nothing on them.
Total cards \(=60\)
Cards with no prize \(=45\)
Probability \(\displaystyle =\frac{45}{60}=\frac{3}{4}\)
