please answer all these questions correctly if you know the answer then only answer else reported​

Answer 1

Step-by-step explanation:

let the set of all nos be (N)

N={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}

S(N)=15

1) Let A be the set of even nos

A={2,4,6,8,10,12,14}

S(A)=7

S(N)=15

probability of even nos = 7/15

2) Let B be the set of odd nos

B={1,3,5,7,9,11,13,15}

N(B)=8

P(B)=8/15

3)Let the set of all prime nos be C

C={2,3,5,7,11,13}

C(N)=6

P(C)=6/15 = 2/5

4) Let the set of 2 digit nos beD

D={10,11,12,13,14,15}

N(D)= 5

P(D)=5/15=5/3

5) Let the set of composite nos be E

E={1,4,6,8,9,10,12}

N(E)=7

P(E)=7/15
