Wait, why do you have lambda=1.2 on the last line of the solution? Shouldn't it be lambda=2 so that the answer is 5e^-2=.67668?

Ncrug,

Thanks for pointing that out.
The last line of the solution should use lambda = 2
(not lambda = 1.2) and the probability should be .6767 .
I'll post a correction shortly.
