Question : A person can hit a target 5 times out of 8 shots. If he fires 10 shots, what is the probability that he will hit the target twice?
Option 1: $\frac{1135 \times 3^8}{8^{10}}$
Option 2: $\frac{1165 \times 3^8}{8^{10}}$
Option 3: $\frac{1175 \times 3^8}{8^{10}}$
Option 4: $\frac{1125 \times 3^8}{8^{10}}$
Correct Answer: $\frac{1125 \times 3^8}{8^{10}}$
Solution : Probability of hitting = $\frac{5}{8}$ Probability of losing = $\frac{3}{8}$ Probability of hitting twice when 10 shots are fired = 10C2$(\frac{5}{8})^2(\frac{3}{8})^8$ = $\frac{10×9×5×5}{1×2}$× $\frac{ 3^8}{8^{10}}$ = $\frac{1125 ×3^8}{8^{10}}$ Hence, the correct answer is $\frac{1125 ×3^8}{8^{10}}$.

Question : If $ \frac{(5x\:-\:y)}{(5x\:+\:y)}=\frac{3}{7},$ what is the value of $\frac{(4x^{2}\:+\:y^{2}\:–\:4xy)}{(9x^{2}\:+\:16y^{2}\:+\:24xy)}$?
Option 1: $0$
Option 2: $\frac{3}{7}$
Option 3: $\frac{18}{49}$
Option 4: $\frac{1}{6}$
Correct Answer: $0$
Solution : Given: $\frac{(5x\:-\:y)}{(5x\:+\:y)}=\frac{3}{7}$ $⇒35x-7y=15x+3y$ $⇒20x-10y=0$ $⇒2x-y=0$---------------(i) $\frac{(4x^{2}\:+\:y^{2}\:-\:4xy)}{(9x^{2}\:+\:16y^{2}\:+\:24xy)}$ = $\frac{(2x\:-\:y)^{2}}{(9x^{2}\:+\:16y^{2}\:+\:24xy)}$ Since from equation (i), we know $2x-y=0$, substituting the value in the above equation, we get, $=\frac{0}{(9x^{2}\:+\:16y^{2}\:+\:24xy)}=$ 0 Hence, the correct answer is $0$.
Question : The ordinary and maximum tolerance limit of sound by human being is:
