Answer 1

a bag caintain red bleu
{R1 R2 R3 B1 B2 B3}
n(S)=6

i) A=event A is getting are red
{R1 R2 R3}
n(S)=3

p(A)=n(A) 3 1
---------- = --- = ---
n(S) 6 2

ii) S={b1 b2 b3}
n(S)=3
B=event B is getting are blue
p(A)=n(A) 3 1
------- = --- = ---
n(S) 3 1

iii) S={R1 R2 R3 , B1 B2 B3}
n(S)=6
n(P)=n(A) 3 1
------ = -- = ---
n(S) 6 2
