1) As it always should be, we need to find the sample space, i.e. the number of total outcomes. We can see that adding them up there are a total of :
[tex]5+7+1+9=12+10=22[/tex]
2) In the table, we can look for the number of favorable events:
[tex]1[/tex]
3) Thus, we can tell that the probability is:
[tex]P(E)=\frac{1}{23}=0.0434[/tex]
Rounding it off to the nearest tenth as requested we can tell:
[tex]4.3\%[/tex]
