If the probability of an event occurring is x, what is the probability of the event not occurring?
1 - x
x - 1
0
\(\frac{1}{x}\)
Correct answer is A
If p is the probability of an event happening(occurring) and the probability of an event not occurring is p1 then p + p1 = 1
p1 = 1 - p
x1 = 1 - x

Each of the interior angle of a regular polygon is 162o. How many sides has the polygon?
8
12
16
20
Correct answer is D
\(\frac{(n - 2)180}{n}\) = 162 (where n = no. of sides)
162n = 180n - 360
162n - 180n = -360
-18n = - 360
n = \(\frac{360}{18}\)
n = 20
Find the volume of a solid cylinder with base radius 10cm and height 14cm.
2203
880cm3>
1400cm3
4400cm3
Correct answer is D
volume of a cylinder = \(\pi r^2h\)
r = 10cm
h = 14cm
= \(\frac{22}{7} \times 10 \times 10 \times 14\)
= 4400cm3
