You put the names of all the students in your class in a paper bag. There are 19 boys and 12 girls. If you draw a name at random, what is P (boy’s name)?
There are a total of 31 students in the class. The probability of drawing a boy's name is equal to the number of boys divided by the total number of students.
P(boy's name) = Number of boys / Total number of students
P(boy's name) = 19 / 31
P(boy's name) ≈ 0.6129
Therefore, the probability of drawing a boy's name at random is approximately 0.6129, or 61.29%.
