Question

A dartboard has 20 equally divided wedges and you are awarded the number of points in the section of your dark lands in if you are equally likely to land in anyways what is the probability you were score more than five points

Answer 1

`Pr =0.75`

Explanation:

Given

See attachment for wedge

Required

`P(x > 5)`

The sample space of the wedge is:

`S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}`

`n(S) = 20`

The outcomes greater than 5 are:

`x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}`

`n(x>5) =15`

So, the probability is:

`Pr =((n(x>5))/(n(S))`

This gives:

`Pr =(15)/(20)`

`Pr =0.75`
