Answer:
[tex]Pr =0.75[/tex]
Step-by-step explanation:
Given
See attachment for wedge
Required
[tex]P(x > 5)[/tex]
The sample space of the wedge is:
[tex]S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]
[tex]n(S) = 20[/tex]
The outcomes greater than 5 are:
[tex]x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}[/tex]
[tex]n(x>5) =15[/tex]
So, the probability is:
[tex]Pr =\frac{(n(x>5)}{n(S)}[/tex]
This gives:
[tex]Pr =\frac{15}{20}[/tex]
[tex]Pr =0.75[/tex]
