When throwing a die two times in a row, choose all of the events that have a probability of 1/6. (or 6/36)

• rolling doubles

• rolling 1 on either die

• rolling a sum of 7

• rolling an even sum

Mrs. Hettinger's blood type is B negative. If two people are chosen at random, what is the probability that they will both have B negative blood?

• 0.02

• 2(.02) = .04

• (.02)² = .0004

• 2²(.02)² = .0016

The most common blood type is 0+. What is the complement of this probability.

• 0.38

• 0.01

• 1 - 0.38 = 0.62

• (0.38)² = 0.1444

Three people are chosen at random. What is the probability that they are all universal donors? (O neg)

• 7%

• 21%

• .03%

• .3%

Four people from this class are chosen randomly. What is the probability that none of them universal donors? (O neg)

• 93%

• 28%

• 3.72%%

• 75%

Blood type probabilities are examples of what type of probability?

• Classical Probability - based solely on mathematical calculations

• Empirical Probability - based on data that has been gathered

• Subjective Probability - based on an educated guess

A password is made up of six digits. How many passcodes are possible?

• 9⁶

• 10⁶

• 9(6)

• 10(6)

A license plate has three digits followed by three letters. How many different digit/letter combinations are possible?

• 3(10) + 3(26)

• 10³ + 26³

• 9³ + 26³

• 10³(26)³
