pls tell answer of 32 and 33 I will follow u and thanx to u​

Answer 1

Step-by-step explanation:

S={1,2,3,4,. ..........100}

n (s)=100

let A be the event of getting prime number less than 30

A={2,3,5,7,11,13,17,19,23,26,27,28}

n (A)=12

p(A)=n(A) = 12 = 3

n(s) 100 25

let B be the event of getting multiple 5 and 7

B={5,7,14,15,20,21,25,28,30,35,40,42,45,49,50,55,56,60,63,65,70,75,77,80,84,85,90,91,95,98,100}

n(B)=31

p(B)=n(B) = 31

n(s) 100
