Six assignments involve library research and four are computer programming exercises. Suppose that a student chooses two assignments, one after the other, at random without replacement. What is the probability that at least one of the assignments is a computer programming exercise?

Apply the аlphа-betа pruning search algоrithm tо the partial game tree abоve, where it is the maximizer’s turn to play, and the game does not involve randomness. The first level is composed of maximizer nodes, the second level is composed of minimizer nodes, and the third level (leaf nodes) is composed of terminal nodes. The utility value for terminal nodes is provided below them, and higher scores are better for the maximizer. Node visitation order is top-to-bottom, left-to-right. Is there any node in the above game tree that can be pruned? Explain why.
