In a typical children's soccer game, there is one goal scored approximately every 18 minutes. the number of goals scored follows a poisson distribution. what would the standard deviation be for the number of goals scored in an entire game? (a game consists of two 45-minute halves.)

2.24

Step-by-step explanation:

The probability formula using a Poisson distribution is:

λ = 90 / 18 = 5 average goals per interval (interval = a game)

So if for example you were interested in the probability of making 2 goals in a game

k = 2

This was just an example,

The standard deviation is
