Currently the code calculates P(n_visitors = 13 | proportion_clicks = 10%): The probability of getting 13 visitors given that the proportion of clicks is 10%.

Change the code to instead calculate P(n_visitors | proportion_clicks = 10%): The probability distribution over all possible numbers of visitors.

Tip: As dbinom is vectorized it suffices to change the value of n_visitors into a vector with the numbers 0, 1, 2, …, 100. Try using the seq function!
