Suppose we pick 4 marbles in a row, each time replacing the marble and thoroughly shaking the jar before picking the next marble. 0 What is the probability that exactly 2 of the marbles have the letter E on them and exactly 2 of the marbles have the letter B on them? Specify this probability to six decimal places. Consider a case in which there are 573 marbles in a jar. Of these 573 marbles 27 of them have the letter H printed on them. 50 of them have the letter E printed on them. 73 of them have the letter A printed on them. 48 of them have the letter I printed on them. 59 of them have the letter B printed on them. 7 of them have the letter D printed on them. 309 of them have the letter C printed on them
