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)?
Ans= 18/31
because
if you add up all the probabilities for the reds it adds up to 18
hence,P(urn-1)=8/18,p(urn-2)=10/13
Probability is number of favorable outcomes by total no. of outcomes
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
