Question

Each card in a set of cards has one of four shapes on it. The table shows the number of times a card with each shape was selected during a game.

Card Game
Shape on Card Number of Times Selected
Square 10
Triangle 18
Circle 8
Pentagon 4


In the next game, 100 cards will be selected. Based on the information in the table, what is the number of times the selected card can be expected to have a square on it?

Enter your answer in the box.

Answer 1

Based on the given information, the probability of selecting a card with a square on it is 10/40, which simplifies to 1/4.

Therefore, in the next 100 card selections, the expected number of times a card with a square on it will be selected is:
(1/4) * 100 = 25

So, the selected card can be expected to have a square on it 25 times.
