1. The problem statement, all variables and given/known data we have 2 boxes with black and white balls inside (box#1 = white balls, box#2 = black).all black and white balls are numbered from 1 to 5. person take out 3 balls from the 1st box and 3 balls from the 2nd box. if success event is when we get first three balls what the probability of success in at least one of the two tasks merely by chance if the choices were made randomly and independently? 2. The attempt at a solution as for me, we have equal probability to get right set of balls (1 + 2 + 3): (1/5)(1/4)(1/3). therefore the probability of success in at least one of the two tasks should be equal two over the number of all possible variations to get 3 balls from 5 in specific order? but, in fact, this reasoning doesn't give a right answer. please fix my attempt to solve this problem.
