Question

Each of two urns contains green balls and red balls. Urn 1 contains 10 green balls and 8 red balls. Urn 2 contains 3 green balls and 10 red balls. If a ball is drawn from each urn, what is P(red and red)?

Answer 1

Ans=  18/31

because
if you add up all the probabilities for the reds it adds up to 18
                      

Answer 2

hence,P(urn-1)=8/18,p(urn-2)=10/13

WHAT IS PROBABILITY?

Probability is number of favorable outcomes by total no. of outcomes

How to calculate ?

No. of favorable outcomes / total no. of outcomes.

Given urn-1- 10 green balls and 8 balls .

and urn -2 - 3 green balls and 1- red balls .

ball is taken out from both the baxes

probability of red ball= p(urn1

P(urn-1)=8/18

p(urn-2)=10/13
