6. (. FacePalm are fake. Assuming that 75% of the news in your newsfeed in FacePalm are indeed fake and you randomly select a news article (selections are independent from one another), what is the probability that: a. the first legitimate news articles you find is the 7th news articles you selected? b. the first legitimate news articles you find is the 6th or 5h news articles you selected? c. the first legitimate news articles you find is among the first 6 news articles you Seventy-five percent of news articles posted on the popular social media app selected? " Arel An adventurer decided to go on a dungeon raid and in order for him to do that, he has to form his party. He decided that he needs 10 mages, 5 healers, 25 assaults, and 15 tanks. If the adventurer's guild currently has 87 mages, 103 healers, 525 assaults, and 370 tanks registered, what is the probability that he meets his needs? 7 --- Food Koala delivers the customer's orders on time 60% of the time.
