At certain times during the year, a bus company runs a special van holding ten passengers from Iowa City to Chicago. After the opening of sales of the tickets, the time (in minutes) between sales of tickets for the trip has a gamma distribution with

= 3 and

= 2

A) Assuming independence, record an integral that gives the probability of being sold out within one hour.

B) Approximate part A using a normal distribution. Is this justified?

-----------------------------------------------------------------------

Not really looking for the answer, just need to know where to begin.

Where would I even start with this?

would it be an

of a gamma distribution?

P(0 < Z < 60)? whats the N(?,?)

or would I use a Chi-square distribution since

is 2 R would be 6...... Kinda lost on where to even begin any help would be appreciated.
