Answer 1

$\huge{Answer ✔}$

A bag contains 6 red balls, 8 white balls, 5 green balls and 2 black balls. One ball is drawn at random from the bag.

Then total number of balls in bag =6+8+5+2+1=22

Total number of out come =22

(i)The event is getting a White ball=number of white ball in bag=8

Then probability=

(ii)The event getting the Red or black=The number of red & black ball in bag=6+8+1=9 (one ball is random)

The probability=

22

9

(iii)The event getting the Not green is total number of ball other then green ball=6+8+2+1=17

The probability=

22

17

(iv) The event getting the Neither white nor black=Total number of balls without white or black ball in bag=6+5=11

The probability= 11/22=1/2
