In which of these examples, binomial distribution can be used? a) finding the best month to launch a new product b) accurately predicting who will be promoted at work c) predicting the score of a cricket match d) probability of getting a certain number of questions correct in an exam

The answer is (d) Accurately predicting who will be promoted at work.

Step-by-step explanation:  We are given four options and asked in which of these four, we can use binomial distribution.

Binomial distribution is used in that experiments where there are only two outcomes, either success or failure.

In the given four options, (a), (c) and (d) are incorrect, because the number of outcomes are not fixed there and hence we cannot use binomial distribution.

Only option (b) will serve our purpose, as we are accurately predicting who is getting promoted at work.

Thus, the correct option is (b).
