A basket contains 9 apples, 8 bananas and 7 oranges. A fruit is picked from the basket, find the probability that it is neither an apple nor an orange

$\begin{align}  & \text{What is the probability that an integer }x\text{ (1}\le \text{x}\le \text{25) chosen at random is divisible by both 2 and 3} \\ & \text{(A) }\tfrac{3}{4}\text{  (B)  }\tfrac{1}{25}\text{  (C) }\tfrac{1}{5}\text{ (D) }\tfrac{4}{25} \\\end{align}$

In how many ways can 3 seats be occupied if 5 people are willing to sit

$\begin{align}  & \text{In how many ways can a students select  2 subjects from 5 subjects} \\ & \text{(A) }\frac{5!}{2!}\text{  (B) }\frac{5!}{3!}\text{  (C) }\frac{5!}{2!2!}\text{  (D) }\frac{5!}{2!3!} \\\end{align}$

$\begin{align}  & \text{If the variance }3+x,6,4,x,7-x\text{ is 4 and the mean is 5, find the standard deviation} \\ & (A)\text{ }\sqrt{2}\text{  (B)  }\sqrt{3}\text{  (C) }2\text{  }(D)\text{ }3 \\\end{align}$
