\(\frac{36}{625}\)
\(\frac{16}{625}\)
\(\frac{12}{25}\)
\(\frac{13}{25}\)
Correct answer is C
Prob(RW or WR) = Prob(RW) + Prob(WR)
\(Prob(R) = \frac{3}{5}:Prob(W) = \frac{2}{5}\\
Prob(RW\hspace{1mm}or\hspace{1mm}WR)=\frac{3}{5}\times\frac{2}{5}+\frac{2}{5}\times \frac{3}{5}\\
\frac{6}{25}+\frac{6}{25}=\frac{12}{25}\)
N136875
N131,875
N126750
N126250
Correct answer is B
The rate of interest charge = 51/2% p.a
The amount borrowed = N125, 000:00
Interest charge \(=\frac{11}{200} of N125,000\\
= 11 \times N625.00 = N6,875.00\)
The amount refunded by the member with interest charge by the cooperative society
N125,000+N6,875.00 = N131,875.00
Given that p = 2, q = -5 and r = - 4, evaluate 3p2 - q2 - r3
101
77
51
-27
Correct answer is C
3(2)2 - (-5)2 - (-4)3
3(4) – (25) – (-64); 12 – 25 + 64 = 51
The sides of two cubes are in the ratio 2:5. What is the ratio of their volumes?
4:5
8:15
6:125
8:125
Correct answer is D
The ratio of the two cubes = 2:5
Volume of the two cubes = 2\(^3\) : 5\(^3\) = 8 : 125
