Are the events "takes Spanish" and "participates in a club" independent events?

• Yes, because P(S) is the same as P(S given C).

• No, because P(S) is not the same as P(S given C).

• Yes, because P(S) is the same as P(C given S).

• No, because P(S) is not the same P(C given S).

Let M represent the event of randomly selecting a male. Let S represent the event of randomly selecting a person that drives a SUV.

Determine if the events M and S are independent.

• Independent

• Not Independent

Are the events "Sports" and "Community Service" independent?

• Yes, because P(S) is the same as P(S Given CS).

• No, because P(S) is not the same as P(S Given CS).

• Yes, because P(S) is the same as P(CS Given S).

• No, because P(S) is not the same as P(CS Given S).

Explain the meaning of P( bike | scooter).

Explain the meaning of P( scooter | bike).

• Probability of owning a bike and scooter.

• Probability of owning a scooter given the person owns a bike.

Calculate P( bike | scooter).

• 0.20/0.80 = 25%

• 0.20/0.40 = 50%

• (0.20)(0.80) = 16%

• (0.20)(0.40) = 8%
