Question

a bag contains 3 red and 5 black balls A ball is drawn at random from the bag what is the probability 1) black ball 2) not black ball​

Answer 1

Answer:

1) 5/8   2) 3/8

Step-by-step explanation:

red balls =3

black balls =

total number of balls the bag contain = 8

1)  probability of black balls =5/8

2) probability of not black balls =8-5=3  3/8

   I hopr it will help full you

Answer 2

Answer:

Step-by-step explanation:

No.of red balls=3

Number of black balls=5

Total number of balls=5+3=8

1.)

Now ,the probability of a black ball=number of black balls / Total number of balls

=5/8

Therefore, the probability of a black ball is 5/8

2.)

Now, the probability of a non black ball=probability of red balls/total number of balls

=3/8

Therefore probability of a ball that is not black=3/8
