(a) Work out the number of yellow counters in the bag. P(Y or R) = 1 – 0. 8 = 0. 2 ÷ 4 = 0. 05 Total buttons: 21 ÷ 0. 35 = 60 buttons Yellow buttons: 60 × 0. 15 = 9 buttons (4) A cube is going to be taken at random from a bag of cubes. The probability that the cube will be black is 0. 5 There must be an even number of cubes in the box. (b) Explain why. If there an odd number of black cubes, 2 x odd = even. If there an even number of black cubes, 2 x even = even (1) (Total for Question 1 is 5 marks)
