Answer: Probability that all three awards will go to a student from School B is [tex]\frac{1}{7}[/tex]
Step-by-step explanation:
Since we have given that
Number of students from school A = 10
Number of students from school B = 12
Number of awards = 3
So, we will need to find the probability that all three awards will go to a student from school B which is given by
[tex]P=\frac{^{12}C_3}{^{22}C_3}\\\\P=\frac{12\times 11\times 10}{22\times 21\times 20}\\\\P=\frac{3}{21}[/tex]
Hence, Probability that all three awards will go to a student from School B is
[tex]\frac{3}{21}=\frac{1}{7}[/tex]
