Answer 1

Answer

c)50

Explanation

S=1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30

n(S)=30

A=probability of event number

A=2,4,6,8,10,12,14,16,18,20,22,24,26,28,30

n(A)=15

p(A)=n(A)/n(S)=15/30=1/2

p(A)=15/30×100=50%

Answer 2

Answer:

C 50% is the answer of this question
