Question

Ther are 2 red, 3 blue and 5 black balls in a bag. A ball is drawn from the bag without looking into the bag. What is the probablity of getting a red ball

Answer 1

Answer:

1/5

Step-by-step explanation:

Total no. of ball is 2+3+5=10balls

P(red balls)=No. of red balls/Total no. of balls

=2/10

=1/5

Answer 2

☞ the total no. of red balls = 2

☞ total no. of balls in a bag = 2 + 3+ 5 = 10

therefore ,

the probability of getting a red ball =

P(E) = number of events happens/

total number of events

P(E) = 2/ 10..

= 1 / 5
