import math
def p(n):
return 393000*((288200/393000)^n * math.exp(-(288200/393000)))/math.factorial(n)
print p(3)
When I run it, I get the following error message:
Traceback (most recent call last):
File "poisson.py", line 6, in <module>
print p(3)
File "poisson.py", line 4, in p
return 393000*((288200/393000)^n * math.exp(-(288200/393000)))/math.factoria
l(n)
