Suppose that for the firing of the four boosters of the Mangalyaan Mars Orbiter, there is a constant probability of failure (say 0.10). Let X be the number of boosters that fail.
What distribution does X follow? Completely identify the distribution. Find the probability that it takes less than 6 draws to get a red King. Find the probability that it takes 6 or more draws to get a red King.
Suppose that X is a continuous random variable with probability density of the form
