Heya Your Answer
_________
It is given that the box contains cards marked with numbers 3, 4, 5, ..., 50.
∴ Total number of outcomes = 48
Between the numbers 3 and 50, there are six perfect squares, i.e. 4, 9, 16, 25, 36 and 49.
∴ Number of favourable outcomes = 6
∴ Probability that a card drawn at random bears a perfect square = Number of favourable outcomesTotal number of outcomes = 6 48 = 1 8
