Beyond the Answer
To find the probability that there will be at least 1 girl on the committee, we can use the complement rule.
First, we need to calculate the total number of ways to choose any 5 students from the group of 23 (10 boys + 13 girls):
Now we can say that the probability of having at least 1 girl is equal to 1 minus the probability of having no girls (which means all boys).
The number of ways to select 5 boys from 10 is:
Thus, the probability of selecting all boys (no girls) is:
Finally, we find the probability of having at least one girl:
Calculating these combinations:
So:
Now plug it into the equation for at least one girl:
Therefore, the probability that there will be at least 1 girl on the committee is
