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)?
A.12/19
B.12/31
C.19/12
D.19/31
D. 19/31
Since there are 19 boys out of a total of 31 students in the class, the probability of drawing a boy's name is 19/31.
