Question 6 An experiment consists of rolling a single die 12 times and the variablex is the number of times that the outcome is 6. Use binomial distribution to find the probability that the

outcome of 6 occurs exactly 3 times

And using the probability mass function we got:

Step-by-step explanation:

Let X the random variable of interest "number of times that 6 appears", on this case we now that:

The probability mass function for the Binomial distribution is given as:

Where (nCx) means combinatory and it's given by this formula:

And we want to find this probability:

And using the probability mass function we got:
