Answer:
Total number of way to pick 3 letters is 6C3 = 20.
Step-by-step explanation:
P(E) = 3/6 = 1/2
P(O) = 3/6 = 1/2
The intersection is P(E n O) = P(E)P(O | E)
= 1/2(2/5)
= 1/5
P( E or O but not both) = P(E and not O) + P(O and not E)
(THis step is easier to understand if you shade in a venn diagram for this):
= [ P(E) - P(E n O) ] + [ P(O) - P(O n E) ]
= 1/2 - 1/5 + 1/2 - 1/5
= 1 - 2/5
= 3/5
The P (E or O or both ) is just the union of the two:
P( E U O) = P(E) + P(O) - P(E n O)
= 1/2 + 1/2 - 1/5
= 4/5

Answer:
Step-by-step explanation:
A) either radius or diameter and height
V = πR²h or πD²h/4
B) Radius is half a diameter, R = 4 cm
C) Rather depends on how they are put together.
Placing the rectangular faces touching would make a cylinder
D) V = 3.14(4²)(2) = 100.48 ≈ 100 cm³
E) divide by 2
i.e. V = ½πR²h
F V = ½(3.14)(4²)(2) = 50.24 ≈ 50 cm³
