... ¾. Column A = (3 /4) 3 = 27/ 64. Column B = one minus the probability of failing the test three times = 1 – 27/ 64 = 37/ 64, which is greater. 28. A: The probability that 4 X is even B: ... 1, 2, 4, 6, 8 and 10. The best answer is B. There are 36 results in total (6 x 6). Column A: there are 4 results with a sum of 10: 4- 6, 6 -4, 2-8, 8-2. and so the probability here is 4/ 36. ... ratio of speeds. The ratio of distances is: 24: 18: 24 or 4: 3 :4. And therefore the ratio in column A = 4/ 3 and the ratio in column B = 1. 4/ 3 > 1 and therefore column A is greater. Column...
