... a sum of 8: 4 -8, 8- 4, 6-6, 10-2, 2-10 and so the probability here is 5/36, which is greater. Column B is greater. 22. A: The probability of receiving “heads” at least once B: 5 /8 AI: A ... balls: 121 8 293 . 2. The probability of two blue balls: 361 8 192. 3. The probability of two yellow balls: 61 8 394 . The total probability in column A = 18 561361121 ... only 8 left. The number of combinations is 9 x 9 x 8 = 6 48 and therefore column B is greater. 20.
