Answer:
[tex]Pr = 0.50[/tex]
Step-by-step explanation:
Given
[tex]n = 30[/tex]
[tex]H = 21[/tex]
[tex]T = 9[/tex]
See attachment for complete question
Required
[tex]P(H)[/tex]
The question requires that we calculate the theoretical probability of landing on the head.
This means that, we have to ignore the given data, and we use the following
[tex]S =\{H,T\}[/tex] --- sample space
[tex]n(S) = 2[/tex] --- sample size
[tex]n(H) = 1[/tex] --- occurrence of Head
So, the theoretical probability is:
[tex]Pr = n(H)/n(S)[/tex]
[tex]Pr = 1/2[/tex]
[tex]Pr = 0.50[/tex]
