Determine the required value of the missing probability to make the distribution a discrete probability distribution. x p(x) 3 0.290.29 4 ? 5 0.320.32 6 0.220.22

The Given is:

P (3) = 0.29

P (5) = 0.32

P (6) = 0.22

The solution will be:

P(4) = 1 – P(3) – P(5) – P(6)

= 1 – 0.29 – 0.32 – 0.22

= 0.17

P(4) is equal to 0.17 according to our simple computation.

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
