Select the statements that are true based on the following given information. D = (x1 x is a whole number)
E = {xl x is a perfect square < 36)
F = {x1 x is an even number between 20 and 30)

1. The expression DU E = E.
2. EU (DN F) IS (25)
3. OFCD
4. (EN F) is the empty set.
5. Set E is Infinite

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
