Step-by-step explanation:
This is a probability related problem.
Probability is the likelihood of an event to occur;
Pr = [tex]\frac{number of possible outcomes}{Total sample space}[/tex]
The sample space here is from 1 to 25 which is 25
A.
Pr of a card marked 8; we have just 1 possible outcome;
Pr(8) = [tex]\frac{1}{25}[/tex]
B.
Pr of drawing a card that is a multiple of 5;
Multiples of 5 = 5, 10, 15 and 25
Pr (multiples of 5) = [tex]\frac{4}{25}[/tex]
C.
Pr of drawing a card with odd numbers:
Number of odd numbers between 1 and 25 = 13
Pr(odd numbers) = [tex]\frac{13}{25}[/tex]
D.
Pr of drawing a number with square number on it;
Square numbers between 1 and 25 = 1, 4, 9, 16 and 25
Pr(square numbers) = [tex]\frac{5}{25}[/tex] = [tex]\frac{1}{5}[/tex]
