If a card is randomly selected from 45 cards
numbered from 1 to 45, find its
probability of holding a perfect square number.
The probability of event occurring is equal to the number of favorable outcomes divided by the total number of possible outcomes in the sample space, .
In this case, event is drawing a card that is a perfect square.
The cards that are perfect squares are 1, 4, 9, 16, 25, and 36, so these are the favorable outcomes for event . Find the probability of event as follows:
Thus, the probability of drawing a card that is a perfect square is .
