WebThat isn't correct. P(X=4) is the probability that Hugo buys 4 packs, regardless of whether the 4th pack contains the card or not. P(X=5), P(X=6), etc will all be zero, because Hugo can't buy more than 4 packs. In other words, P(X=4) is the probability that the Hugo gets the card in the 4th pack plus the probability that he doesn't get the card ...
