# Probability watch

1. 1. A fair five sided spinner has sides numbered 1,1,2,3,3. The spinner is spun twice. Find the probability that the spinner will stop at 1 at least once.

2. A card is dealt from a well-shuffled ordinary pack of 52 playing cards.
(i) Find the probability that the card is
(a) the 4 of spades
(b) the 4 of spades or any diamond

(ii) The first card is dealt is placed face-up on the table. It is the 3 of diamonds. What is the probability that the second card is from a red suit?

3. What have you tried?
4. For the first part would it make it easier for you if I asked to work out the probability that the spinner doesn't stop on a 1 on either spin?

Is there a particular part you are stuck on?
5. 1. make a tree diagram ?
