Question

There are 2 boxes, one has 20 red balls and other has 2 red and 8 blue balls. what is the probability of getting a red ball?
Please answer I will mark as brainliest if the solution is correct ​

Answer 1

probablity of event = 20+2/20+2+8

=22/30

=11/15

Answer 2

Answer:

LET the sample space of1st box be S

Therefore,. S=(R1,R2,R3,R4,.........,R20)

Therefore n(S)=20

LET the sample space of 2nd box be Z

Therefore Z =(R1,R2,B1,B2,.......,B8)
