P(A) = 0.72 P(B) = 0.28
P(A and B) = 0.14

a) P(A or B)
b) P(A^c)
c) P(B^c)
d) P(A^c and B^c) or P(neither A not B)
e) P(A or B^c)
f) P(A^c or B)

^c meaning the complement of

i) or

- union, U

- addition, +

ii) and

- intersection, (upside down U)

- multiplication, x

Let, height of the Building = x

Height of the Tower = y

Height of the tower is 5 times from height of the building = y = 5x

Height of the tower is 52 meter taller than the building = y-x = 52

put 5x instead of y in the equation y-x=52

5x-x=52

4x=52

x=52/4

x=13 meter

y=5x

y=5(13)

y=65 meter
