working out probabiblities (help)
A computer games retailer knows that there is a 62% chance that a customer coming into its store will buy a game out of the top ten games chart. 8 individual customers visit the shop in one hour.
(i) What is the probability that exactly 6 of them will buy a game from the top ten chart?
(ii) What is the probability that no more than 7 will buy a game from the top ten chart?
can someone show me how to do this?? im preparing for my exams and need to understand this (im looking at past exams). And if possible could you recommend me a site to understand this? thanks
