5/8
7/8
9/16
14/25
39/40
Correct answer is A
No. of possible outcome = 40
No. of expected outcome = 16 + 9 = 25
Probability = 25/40 = 5/8
If Q = (all perfect squares less than 30) and P = (all odd numbers from 1 to 10). Find Q ∩ P.
(1, 4, 9, 16, 25)
(1, 3, 4, 5, 7, 9, 16, 25)
(1, 3, 5, 7, 9)
(1, 9)
Φ
Correct answer is D
Q = {1, 4, 9, 16, 25} P = { 1, 3, 5, 7, 9}
Q ∩ P = { 1, 9}

60o
Correct answer is D
\(\Delta RPS\) = Isosceles triangle
\(\therefore < RPS = \frac{180° - 90°}{2}\)
= 45°
In \(\Delta QPR\),\(\sin < QPR = \frac{1}{2}\)
= 30°
\(\therefore < QPS = 30° + 45° = 75°\)
33o
40o
90o
180o
270o
Correct answer is D
Circumference = 2πr
2 x 22/7 x 3.5 ≅ 22m
22m = 360o
11m = 360/22 x 11 = 180o
