Question

a bag contains 16 red balls and 4 blue balls . a ball is taken at random from the bag . what is the probability that is at ​

Answer 1

Answer:16/20 AND 4/20

Step-by-step explanation: If red ball is taken out it will be 16 by 20

20=16+4 the total

and if blue ball is taken out it  will be 4/20  because there are 4 balls in a bag.

Answer 2

1. possible outcomes =16+4=20

favorable outcomes =16.

p( red ball) =16/20

=4/5

2. possible outcomes =20

favorable outcomes =4

p( blue ball) = 4/20

= 1/5
