Handling Data (13) Probability Sample Spaces 1. A coin is tossed and a die is rolled at the same time.
(a) Draw a sample space diagram to show all the possible outcomes.
(b) What is the probability that
(i) the coin lands heads up and the die lands on a six?
(ii) An even number is obtained on the die with the coin showing Tails?
2. Two dice are thrown together.
(a) Draw up a table to show a list of all possible outcomes.
(b) What is the probability of throwing:
(i) a total greater than 8,
(ii) a double,
(iii) a total which is an odd number,
(iv) a total which is exactly divisible by 3?
3. Pupils in year 7 had to design a Logo using any two shapes. John’s
design is shown opposite.
Next he had to paint his logo and had a choice of 4 colours: Red,
Green, Yellow or Blue. John could not decide which colours to use and
so picked at random one colour from the four for his top shape and
again one colour from the four for his second shape.
(a) Draw up a table of all possible outcomes for John’s Logo.
(b) What is the probability of picking yellow for the first shape and red for the second shape?
(c) What is the probability of picking the same colour for the complete logo?
(d) What is the probability that one shape will be red and the other green?
4. One bag contains 5 counters where 3 are black and 2 are white. A second bag contains 4
counters where 3 are white and 1 is black. A counter is selected, at random, from each bag.
(a) List all the possible outcomes for the two selected counters.
(b) What is the probability of selecting
(i) two black counters
(ii) one black counter and one white counter?

5. Asif and Joanne are playing a game called “Paper, scissors and Rock”. Each person places a
hand behind their back and after a count of five shows their hand in the shape of either paper,
scissors or a rock. The winner depends on rock beats scissors, scissors beats paper and paper
beats rock. If they both show the same shape then it’s a draw.
(a) Draw up a table to show a list of all the possible outcomes when Asif and Joanne play.
(b) What is the probability that
(i) Asif shows paper and Joanne shows a rock,
(ii) They both show the same shape,
(iii) Asif wins?
6. The four Aces and the four twos are taken from an ordinary pack of playing cards and placed
into two piles. A card is selected at random from the set of four Aces and one from the set of
four Twos.
(a) Draw a sample space diagram for the possible combinations of the two cards.
(b) What is the probability that the two cards are
(i) both clubs,
(ii) both red,
(iii) both of the same suit?
