Answer 1

here is ur answer buddy....
sample space:{1,2,3.......,100}
n(s)=100
I)
let A be an event of getting a prime number less than 30
A:{2,3,5,7,13,17,19,23,19}
n(A)=9
p(A)=9/100

ii)
let B be an event of getting a multiple of 5 and 7
B:{35,70}
n(B)=2
p(B)=2/100

iii)
let C be an event of getting multiple of 5
C:{5,10,15,20,25,30,35........,100}
n(C)=20
p(C)=20/100

let D be an event of getting multiple of 7
D:{7,14,21,28,35,42,49,,56,63,70,77,84,91,98}
n(D)=14
p(D)=14/100

required probability=p(C)+p(D)
=>(20/100)+(14/100)
=>(20+14)/100
=>34/100

hope it helps......
