Answer:
34%
Explanation:
5 girls + 7boys = 12 students
then:
7 / 12 = 0.5833
0.5833*100 = 58.33%
The probability of getting a boy among all the students is 58.33%
Now, If the teacher randomly picks seven students the probability that he will pickall boys is:
7/12 = 0.5833
then
0.5833*58.33 = 0.34
0.34*100 = 34%
