Answer:
[tex]\frac{7}{11}[/tex]
Step-by-step explanation:
Probability is defined as the likelihood of an event occurring.
-The probability of being selected is :
[tex]P_s=\frac{4}{11}[/tex]
-The probability of not being selected is :
[tex]P_{ns}=1-P_s\\\\=1-\frac{4}{11}\\\\=\frac{7}{11}[/tex]
Hence, the probability of John not being selected is [tex]\frac{7}{11}[/tex]
