Suppоse we hаve а bаg cоntaining 100 marbles: 20 red marbles, 30 green marbles, and 50 blue marbles. We randоmly select 7 marbles from the bag without replacement. The probability that any randomly selected marble is red is 0.2, green is 0.3, and blue is 0.5. Compute the probability of selecting exactly 2 red marbles, 2 green marbles, and 3 blue marbles.
