Independent Mutual Exclusive

If you roll one die, what is the probability of getting an odd number or a 4?

• 2/3

• 1/3

• 1/2

• 1/6

Which formula do you use when two events are mutually exclusive?

• P(A or B) = P(A) + P(B)

• P(A or B) = P(A) + P(B) - P(both)

• P(A and B) = P(A) * P(B)

• P (A and B) = P(A) * P(B|A)

if the occurence of one event does not affect the occurence of other,

then they are called______events

• equally likely

• mutually exclusive

• Independent

• Exhaustive

Two events are said to be mutually exclusive events if

• the events occur at the same time

• the events have same probability

• the events cannot occur at the same time

• the events are unlike

Determine if the events are independent or dependent.

• Independent

• Dependent

Determine if the events are independent or dependent.

• Independent

• Dependent

When flipping a coin once, the possible outcomes (heads or tails) are:

• Independent

• Mutually exclusive

If A and B are mutually exclusive then...

• They are always independent

• They may be dependent or independent

• They are always dependent

• 5/6

• 1/36

• 1/3

• 1/6
