A bag contains 3 red balls and 1 blue ball. A second bag contains 1 red ball and 1 blue ball. A ball is randomly picked from eac

Firlakuza [10]

Answer:

"2.82" seems to be the correct solution.

Step-by-step explanation:

As we know,

A bag (Bag A) contains,

Red balls = 3

Blue ball = 1

A second bag (Bag B) contains,

Red balls = 1

Blue ball = 1

Now,

⇒ P(Bag A, red ball) = $P(A)\times P(r)\times P(r)$

On substituting the values, we get

⇒ = $\frac{1}{2}\times \frac{3}{4}\times \frac{2}{3}$

⇒ = $\frac{1}{4}$

Similarly,

Probability of second bag will be:

⇒ P(Bag B) = $\frac{1}{2}$

hence,

In the first bag (Bag A), the expected number of red balls will be:

⇒ $E(n)=\Sigma P(n)\times n$

On substituting the values, we get

⇒ $=3 (\frac{1}{4})+2(\frac{1}{8} )+4(\frac{1}{24} )+3(\frac{1}{12} )+3(\frac{4}{20} )+4(\frac{1}{20} )+2(\frac{3}{20} )+\frac{2}{20}$

⇒ $= \frac{169}{60}$

⇒ $=2.82$
