Answer:
P = 1/6 or 0.1667
Step-by-step explanation:
Let A,B and C be the three events and 1,2 and 3 be the three dates. The sample space for this problem is:
{A1,B2,C3} {A1,B3,C2} {A2,B1,C3} {A2,B3,C1} {A3,B1,C2} {A3,B2,C1}
There are six possible outcomes and since there is only one correct answer, the possibility of guessing all 3 questions right is:
P = 1/6
P = 0.1667
Given:
Number of girls = 20
Number of boys = 30
The president must be a girl and the vice president a boy
To find:
Number of ways to choose a president, vice president, and secretary.
Solution:
The president must be a girl and the vice president a boy. So, out of three students 1 is girl and 1 is boy. Third student can be a girl or a boy.
Total number of ways = Selecting 2 boys and 1 girl + Selecting 1 boy and 2 girls
Therefore, the required number of ways is 12500.
