    Asteroid Momentum & Starbase Alpha Impact

    An asteroid is spotted moving directly toward the center of Starbase Alpha. The frightened residents fire a missile at the asteriod, which breaks it into two chunks, one with 2.4 times the mass of the other. The chunks both pass the starbase at the same time. If the lighter chunk passes 1800 m...

    Approx. Probability of 20 Chips with Lifetime < 1.8M Hours in a Batch of 100

    Why even use a binomial approximation? Let Y denote the number of computer chips whose lifetimes are less than 1.8*10^6. Then Y~Bin(100, 0.9082).
