Each time the ball is thrown into the bowl, the probability of hitting the 3-point zone is 0.1, the probability of hitting the 2-point zone is 0.2, and the 1-point zone is 0.3. The number of points scored by throwing the ball into the bowl three times is a random variable. Set a probability distribution of the values of this variable and calculate the mean and variance. What is the probability that the sum of the points collected exceeds 6?
