Question

In a second grade class containing $14$ girls and $8$ boys, $2$ students are selected at random to give out the math papers. What is the probability that the second student chosen is a girl, given that the first one was a boy?

Answer 1

Finding the probability of that second student chosen is boy :

Total number of students $=14+8=22$

Out of those students, number of girls students is equal to $14$

And number of boys is equal to $8$.

Now, The probability that the second student chosen is girl

It given that, first selected student is a boys,

Probability $=\frac{14}{21}=0.66$

Hence, the probability that second student chosen is girl is $0.66$.
