Please helppp Enter the first 4 terms of the sequence defined by the rule given.
f(1) = 9, f(n)=f(n − 1) – 3
The first 4 terms are

Probability that the fifth ball selected is red = 0.705

Step-by-step explanation:

Let

= Number of red balls after the 4th turn

⇒  ∈ { 0, 1, 2 }

Then,

P =

⇒

Now,

P(5th ball is red | = 2 ) = 0. +

                                         =  

                                        = 0.705

∴ we get

Probability that the fifth ball selected is red = 0.705
