When it comes to tossing dice, the probability of getting a certain roll...

Is independent of any other rolls

Depends on what you just rolled before

Tim is rolling a die. Tim says "P(getting a 6 | I just got a 4) =P( getting a 6)". Is he correct? Why?

He is right because rolls of dice are independent.

He is wrong because conditional probabilities much take the condition into account.

He is wrong because you can't get a 6 and a 4 at the same time.

What is going on in the tree diagram?

A person has 3 choices for sandwich, 2 choices for side and 2 choices for drink. There are a total of 12 possible outcomes.

A person has 3 choices for sandwich, 2 choices for side and 2 choices for drink. There are a total of 7 possible outcomes.

A person has 3 choices for sandwich, 6 choices for side and 12 choices for drink. There are a total of 216 possible outcomes.

When would you use P(A)xP(B)

When you want the probability of A AND B both occurring and A and B are independent

When you want the probability of A OR B occurring and A and B are independent

When you want the probability of A and B both occurring and A and B are dependent

When you want the probability of A OR B occurring and A and B are dependent

Why is rolling a sum of 7 on 2 dice more likely than rolling a 3?

There are more ways to add up to 7 with 2 dice than adding to 3

Bigger numbers are always more likely

3 is the least likely sum of two dice

If P(A) > P(B), this means...

Event A is more likely to occur than event B

Events A and B cannot both occur

Event A is less likely to occur than event B
