In a math class there are 8 male students and 7 female students. A student is
randomly selected to go to the front office and leaves. A second student is
randomly selected to go to the office. What is the approximate probability that
both students that left were a male students?
A.) 28.4%
B.) 26.7%
C.) 50%
D.) 25%

Step-by-step explanation:

B.)since there are more male then female
