Expected value of bb = 1.79
What is expectation?
At first it is important to know about probability of an event.
Probability gives us the information about how likely an event is going to occur
Probability is calculated by Number of favourable outcomes divided by the total number of outcomes.
Probability of any event is greater than or equal to zero and less than or equal to 1.
Probability of sure event is 1 and probability of unsure event is 0.
Suppose x is a random variable with the probability function f(x). suppose
are the values corrosponding to the actual occurance of the event and be the corrosponding probabilities.
Expectation is given by the formula =
Expected value of bb =
0.35 ˣ 0 + 0.20 ˣ 1 + 0.15 ˣ 2 + 0.10 ˣ 3 + 0.07 ˣ 4 + 0.08 ˣ 5 + 0.04 ˣ 6 + 0.01 ˣ 7
0 + 0.20 + 0.30 + 0.30 + 0.28 + 0.40 + 0.24 + 0.07
= 1.79

Lets solve f(5). First, replace all "n"s in the equation with 5s. F(5+1)=F(5)-2. This means that F(6)=F(5)-2, F(5)=F(4)-2, F(4)=F(3)-2, F(3)=F(2)-2, and F(2)=F(1)-2. Because we know F(1)=18, F(2)=16, F(3)=14, F(4)=12, and F(5)=10.
