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) = 
On substituting the values, we get
⇒ = 
⇒ = 
Similarly,
Probability of second bag will be:
⇒ P(Bag B) = 
hence,
In the first bag (Bag A), the expected number of red balls will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
It’s b because you add 4 and there you go hope this

Answer:
-11/10 or -1 1/10
Step-by-step explanation:
Change to improper fractions format
1 6/10 becomes 16/10
2 7/10 becomes 27/10
16/10 - 27/10 = -11/10
-11/10 is also written -1 1/10
I think the answer is br/b-r = a
