10/21
Possible out comes(E) or Favourable OUTCOMES are
E1.2 red ball or
E2.2 green ball or
E3.1 red and 1 green
Number of selecting 2 BALLS from two red balls n(E)=2C2=1
Number of ways of selecting 2 balls from 3 green balls n(E2)=3C2=3
Number of ways of selecting 1 red ball and 1 green ball n(E3)= 2C1*3C1=2*3=6
Sample SPACE S=Number of ways of selecting 2 balls from 7(2+3+2) balls n(S)=7C2=21
n(E)=n(E1)+ n(E2)+ n(E3)=1+3+6=10
Required probability P(E)=n(E)/n(S)=10/21
