Three couples and two individuals (eight total people) have been invited to an investment seminar and have agreed to attend.

- Suppose the probability that any particular couple or individual arrives late is .4 (a couple will travel together in the same vehicle, so either both people will be on time or else both people will arrive late).

- Assume that different couples and individuals are on time or late independently of one another.

- Calculate the probability that 6 or more people arrive at the seminar on time.

Hint: consider the disjoint cases: exactly 6 are on time, exactly 7 are on time, exactly 8 are on time, then think of all the combinations of couples and individuals that yield that amount.

Please dont copy the answer from another post and explain !!!
