The number of calls coming to the call center follows Poisson distribution. On the average 90 calls arrive every hour on Mondays between 10 and 11 a.m. This means that mean number of calls per minute is 1.5. The probability that exactly three calls will arrive in given minute is:
A: .2152
B: .1255
C: .3205
D: .1451
E: .5232
