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. Square 10 triangle, 18 circle eight and pentagon four in the next game 100 cards will be selected based on its information in the table. What is the number of the times the selected card can be expected to have a square on it
To find the expected number of times the selected card will have a square on it, we use the formula:
Expected value = (Number of times square was selected / Total number of cards selected) * Total number of cards selected
In this case, for squares:
Expected value = (10 / 40) * 100
Expected value = (1/4) * 100
Expected value = 25
Therefore, the selected card can be expected to have a square on it 25 times.
