The table below from the American Red Cross shows the distribution of blood types in the United States.

Blood Type	Distribution
O	45%
A	40%
B	11%
AB	4%

I don't understand the difference in determining the actual versus probable. Can you explain and show how to determine these?

A local hospital holds a blood drive. By the end of the first day, 200 volunteers had donated blood. 60% of the units collected were type O and 25% were Bloodtype A.

How did the calculated probability compare to the empirical results?

Match each type, with the correct amount.

Actual Blood A, Expected Blood A, Actual type O, Expected type O

25 units, 50 units, 80 units, 90 units, 120 units, 60 units, 40 units, 45 units
