proportion_clicks <- runif(n_draws, min = 0.0, max = 0.2)
n_visitors <- rbinom(n = n_draws, size = n_ads_shown,
prob = proportion_clicks)
prior <- data.frame(proportion_clicks, n_visitors)
# Create the posteriors for video and text ads
posterior_video <- prior[prior$n_visitors == 13, ]
posterior_text <- ___
# Visualize the posteriors
hist(posterior_video$proportion_clicks, xlim = c(0, 0.25))
