\(\frac{4}{5}\)
\(\frac{3}{4}\)
\(\frac{3}{5}\)
\(\frac{1}{20}\)
Correct answer is C
prob(p) = \(\frac{1}{5}\)
prob(Q) = \(\frac{1}{4}\)
Prob(neither p) = 1 - \(\frac{1}{5}\)
\(\frac{5 - 1}{5} = \frac{4}{5}\)
prob(neither Q) = 1 - \(\frac{1}{4}\)
\(\frac{4 - 1}{4} = \frac{3}{4}\)
prob(neither of them) = \(\frac{4}{5} \times \frac{3}{4} = \frac{12}{20}\)
= \(\frac{3}{5}\)
If log 5.957 = 0.7750, find log \(3 \sqrt{0.0005957}\)
4.1986
2.9250
1.5917
1.2853
Correct answer is B
\(3 \sqrt{0.0005957}\)
\(\begin{array}{c|c} \log No(0.0005957) & \frac{1}{3} \log \frac{1}{3} \\ \hline (0.0005957)^{\frac{1}{3}} & 4.7750 \times \frac{1}{3} \\ & 6 + 2.7750 \\\hline & 3 \\\hline & 2.9250\end{array}\)
\(\frac{5}{9}\)
1\(\frac{4}{9}\)
\(\frac{1}{3}\)
\(\frac{2}{9}\)
Correct answer is C
p = { 1, 2, 3}
Q = {2, 3, 5}
prob(prime number) = prob(1 and 2) or
= prob(2 and 3) or
= prob(3 and 2)
There are three possibilities of the sum being prime
Total possibility = 9
probability(sum being prime) = \(\frac{3}{9}\)
= \(\frac{1}{3}\)

\(\frac{1}{4}\)
\(\frac{1}{3}\)
\(\frac{2}{3}\)
\(\frac{3}{4}\)
Correct answer is C
There are 3 triangles: \(\bigtriangleup\)MRS, \(\bigtriangleup\) and \(\bigtriangleup\) PRQ
Area PRMS has 2 triangles: \(\bigtriangleup\) MRS and \(\bigtriangleup\) RSP
the fraction = \(\frac{2}{3}\)
