Explanation Given Information: The number of companies in which the investment was made is, n = 10 , the probability that a company will be a stock market success is p = 0.2 and the probability a company will not be a stock market success is q = 1 − p . Formula used: If the number of successes in a sequence of n independent Bernoulli trials is X , then P ( X = x ) = C ( n , x ) p x q n − x Where n = Number of trials p = Probability of success q = Probability of failure Calculation: Consider the number of companies in which the investment was made is n = 10 , the probability that a company will be a stock market success is p = 0.2 and the probability a company will not be a stock market success is q = 1 − p . Also, the Bernoulli trials where in each trial an internet startup company is selected and it is observed that the “success” in these trials will be the stock market success of the company. The probability that at least 1 will be a success implies that either 1 or more than 1 of the 10 companies will be a success
