Answer:
Step-by-step explanation:
[tex]\frac{(3,2)}{(8,2)} = \frac{3}{28}[/tex]
Answer:
The probability that both of them have done their homework is [tex]\frac{3}{28}[/tex].
Step-by-step explanation:
Consider the provided information.
In a class of 8, there are 3 students who have done their homework.
2 students chosen and we need to find the probability that both of them have done their homework.
The probability that first student have done their homework is:
[tex]\frac{3}{8}[/tex]
The probability that second student have done their homework is:
[tex]\frac{2}{7}[/tex]
Now the probability that both of them have done their homework is:
[tex]\frac{3}{8}\times \frac{2}{7}=\frac{3}{28}[/tex]
Hence, the probability that both of them have done their homework is [tex]\frac{3}{28}[/tex].
