And replacing we got:
Step-by-step explanation:
Let X the random variable of interest "number of times that we select a blue ball", on this case we now that:
The probability is always the same since we replace the ball selected in each trial.
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 replacing we got:
