Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcome, where p _i represents the probability of observing the with outcome. What would be the formula of an expected count in this situation Choose the correct answer below. The expected counts for each possible outcome are give by E_2=n. The expected counts for each possible outcome are give by E_2 = n/p_i. The expected counts for each possible outcome are give by E_2 = p_i. The expected counts for each possible outcome are give by E_2 = np_i.

Solution

For each outcome, the expected number is Ei = n pi.

Thus, it is OPTION D. [ANSWER, D]
