VJEROJATNO sam gledao Suits već 5 puta | I’ve PROBABLY watched Suits five times already #3

Louis Litt na streljani puca na okruglu metu, a pogađa ju s vjerojatnošću 80\%. Na natjecanju dobiva bod za svako gađanje u kojem pogodi metu, ali gubi tri boda za svaki promašaj (moguće je imati i negativne bodove). Harvey mu je obećao da će se ići kupati u blatu s njim, ako na natjecanju bude imao pozitivan broj bodova. Koliko najmanje puta mora gađati da bi bio 90\% siguran da ima pozitivan broj bodova?
Louis Litt is shooting at a round target, and he hits it with a probability of 80\%. In the competition, he earns one point for each hit, but loses three points for each miss (it is possible to have a negative score). Harvey promised to go mud-bathing with him if he ends the competition with a positive score. What is the minimum number of shots Louis needs to take to be 90\% sure of having a positive score?
