Anon is required to sell atleast $50 of candy bars There are infinite houses in the neighborhood, and each house is guaranteed to buy a bar. Anon has bar A which sells for $2, bar B which sells for $5, and bar C which sells for $10. The chance for each house to buy each bar is always 0.6, 0.3, and 0.1 (the houses will always buy something). Anon will go house to house until he has atleast 50 dollars, what is the probability that Anon will visit n houses?
I have no idea how to model the distribution of this random variable, any advice? thanks
