Question

A bag contains 2 red and 3 black balls. Find the probability distribution of the number of red balls if 2
balls ae drawn with replacement from the bag.

Pls answer ASAP without spamming in an exam

Answer 1

Answer:

1/10

Step-by-step explanation:

The bag contains 5 balls in all. Random picking of 2 balls will be 5C2 = 10 in number. Since the sample space S is the set of all such outcomes n(S) = 10.

Now the desired event E is the set of all outcomes which gives us 2 red balls. There are 2 red balls and so the number of chances are 2C2 = 1. i.e., n(E) = 1.

Hence the probability of getting two red balls out of 7 balls is n(E)/n(S) = 1/10
