The probability that a flight from a certain airline arrives on time is 0.8. Find the probability that in a random sample of 12 flights:

Question 1 : Exactly 10 of the flights were on time.

Question 2 : At least 10 of the flights were on time.

Question 3 : At most 10 of the flights were on time.

any help wud be greatly appreciated!

i think its (.8)^10 for the first one or something like that but i'm prob wrong..
