9. Each of 100 students in the class can only take 1 computer science class each, between the four classes discrete-math, intro-programming, data-structures, and computer-architecture. Each student (independently of others) takes discrete-math with probability 0.3, intro-programming with probability 0.4, data-structures with probability 0.1, and computer-architecture with probability 0.2. What is the probability that all of the following conditions are satisfied simultaneously? . 29 sign up for discrete-math . 41 sign up for intro-programming . 6 sign up for data-structures . and 24 sign up for computer-architecture
