a) 32/99 Case 1: Red ball is picked from Bag 1 Probability = 5/9 Bag 2 will now have 4 red and 7 black. A red can be picked with probability = 4/11 Case 1 probability is 5/9 x 4/11 = 20/99 Case 2: Black ball is picked from Bag 1 Probability = 4/9 Bag 2 will now have 3 red and 8 black. A red can be picked with probability = 3/11 Case 2 probability is 4/9 x 3/11 = 12/99 So, possibility of red from second bag = 20/99 + 12/99 = 32/99

Can you solve this question with clear explanation ?
latest answer
Let log N = â??2.4678 = â??2 â??1 + 1 â?? 0.4678 = â?? 3 + .5322 As given, for mantissa 0.5322, the number is 3406 The characteristic is â??3, therefore the number is less than one and there must be two zeros just after the decimal point. Hence, antilog â??2.4678 = 0.003406
