Answer:
Option e) all statements is correct
I) ∅ ∈ U and n (U) = 10. II) ∅ ⊂ U and n (U) = 10.
III) 5 ∈ U and {5} ⊂ U.
IV) {0,1,2,5} ∩ {5} = 5. are all true
Explanation:
Given that the set U = {0,1,2,3,4,5,6,7,8,9}
To find the statements which is true to the given universal set:
Given statements are I) ∅ ∈ U and n (U) = 10.
II) ∅ ⊂ U and n (U) = 10.
III) 5 ∈ U and {5} ⊂ U.
IV) {0,1,2,5} ∩ {5} = 5.
For :
A universal set is the collection of all elements in a particular manner.
All other sets are subsets of the universal set, the universal set is denoted by U.
Hence I) ∅ ∈ U and n (U) = 10.
II) ∅ ⊂ U and n (U) = 10.
III) 5 ∈ U and {5} ⊂ U.
IV) {0,1,2,5} ∩ {5} = 5. are all true by the definition of Universal set.
∴ Option e) all statements is correct
