Costa Rica Primera Division Playoffs (Alajuelense @ Saprissa): Will a GOAL be SCORED in the FIRST TEN MINUTES?

10:30PM
Yes: Goal scored in first 10 minutes
No: No goal scored in first 10 minutes

Inputs to Solve

##### User Estimates #####

expected_G_Per_Game = 2.25
# over / under

## Inputs Defined in the Problem

GOALS = 0
time = 10

Method to Solve

[1] Estimate lambda (l_) (arrival rate of GOALS per 10 minutes)
[2] Use the Poisson Distribution to compute the probability of zero GOALS SCORED in the FIRST TEN MINUTES (p_0)

## [1]

l_ = float(expected_G_Per_Game * time) / 90
print("The total expected GOALS a 10 minute period is %s" % round((l_),3))

The total expected GOALS a 10 minute period is 0.25

## [2]

import math

p = math.exp(-l_)*(l_**GOALS)/(math.factorial(GOALS))

print("The probability of k events occuring in an Poisson interval = e^(-lambda) * ((lambda^k)/k!)")
print('where k = 0 and lambda = %s' % round(l_,3))
print('')
print("p = e^(-%s) * (%s^%s)/%s!" % (round(l_,3),round(l_,3),GOALS,GOALS))

The probability of k events occuring in an Poisson interval = e^(-lambda) * ((lambda^k)/k!) where k = 0 and lambda = 0.25

p = e^(-0.25) * (0.25^0)/0!

Solution

print("The probability of %s GOALS in the FIRST TEN MINUTES is %s" % (GOALS,round(p,3)))

The probability of 0 GOALS in the FIRST TEN MINUTES is 0.779
