Made with pylab (started with "ipython -pylab"). Here is the code:
def inv_prob(n):
if n == 0:
return 1
if n > 365:
return 0
return inv_prob(n-1)*(1-(n-1.)/365)
def probarray():
arr=[]
for people in range(364):
arr.append(1-inv_prob(people))
return arr
def qrobarray():
arr=[0]
for people in range(399):
arr.append(1-((1-arr[people])*(1-1./365)))
return arr
plot(qrobarray())
plot(probarray())
text(200,.5,'q(n)', color='blue')
text(35,.6,'p(n)', color='green')
