Consider events $A, B, C, D, E$ of the sample space $S=$ ( $n: n$ is an integer such that $10 \leq n \leq 20$ ) given by: A is the set of all even numbers. $B$ is the set of all prime numbers. $C=\{15\}$ D is the set of all integers $\leq 16$. $E$ is the set of all double digit numbers expressible as a power of 2 . $B$ and $C$ are

• Correct answer
  A

  Mutually exclusive events but not exhaustive events
• B

  Compound events
• C

  Mutually exclusive and exhaustive events
• D

  Elementary events

Hence, the correct answer is option: 'A'.
