the ball drawn is (i) red ? (ii) not red?
(2 points)
O 3/8,0
O 5/8,0
0.37, 0.6
O None of these​

Answer 1

Answer:

Hi..hope you like my answer.

Step-by-step explanation:

Number of red balls =3

Number of black balls =5

Total number of balls =5+3=8

(i) Probability of drawing red balls =

Number of red balls/Total Number of balls

= 3/8

(ii) Probability of drawing black balls =

Number of black balls/Total Number of balls

=5/8

Answer 2

Answer:

none of these

Step-by-step explanation:

probability of a red ball = no. of red balls / total no. of balls

probability of a red ball = 3/8

probability of a non- red ball = no. of black balls / total no. of balls

probability of a non-red ball = 5/8
