Answer:
a) 0.05
b) 0.0526
c) 0.0625
Step-by-step explanation:
Data provided in the question:
Total number of students in a class = 20
a) since it is Monday, no student will be selected already.
Therefore,
There are 20 students from which one can be selected
Thus,
P(Serena is selected on Monday) = 1 ÷ [Number of students available]
= 1 ÷ 20
= 0.05
b) On Tuesday, one student has already been selected on Monday
Therefore,
There are (20 - 1) = 19 students from which one can be selected
Thus,
P(Serena is selected on Tuesday) = 1 ÷ [Number of students available]
= 1 ÷ 19
= 0.0526
c) On Friday , 4 student has already been selected on Monday
Therefore,
There are (20 - 4) = 16 students from which one can be selected
Thus,
P(Serena is selected on Tuesday) = 1 ÷ [Number of students available]
= 1 ÷ 16
= 0.0625
