Question

The soccer team won 80% of its games this season. If the team won 12 games, how many games did it play?

Answer 1

The team played 15 games.

Explanation:

It an be solved with the help of a binomial distribution.

Probability of the soccer team wining a game`p=0.8`
Average Number of games it has won is `barx=12`

Then -

`barx=n.p`
`12=n xx 0.8`

solve it for `n`

`n xx 0.8=12`
`n=12/(0.8)=15`

The team played 15 games.
