In a typical children's soccer game, there is one goal scored approximately every 18 minutes. The number of goals scored follows
Alja [10]

Answer:

2.24

Step-by-step explanation:

The probability formula using a Poisson distribution is:

P(k\ events) = \frac{\lambda^{k}e^{-\lambda}}{k!} \\\lambda\ is\ the\ average\ number\ of\ events\ per\ interval \\e\ is\ euler's\ number \\k\ is\ the\ number\ of\ events\ you\ want\ to\ calculate

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

P(k = 2) = \frac{5^{2}e^{-5}}{2!} = 0.084

This was just an example,

The standard deviation is \sqrt{\lambda}

\sigma = \sqrt{\lambda} \\\sigma = \sqrt{5} \\\sigma = 2.24
