MCQ
A number is selected from numbers 1 to 25. The probability that it is prime is:
- A$\frac{2}{3}$
- B$\frac{1}{6}$
- C$\frac{1}{3}$
- ✓$\frac{9}{25}$
✓
Answer
Correct option: D.
$\frac{9}{25}$
$\frac{9}{25}$
Solution:
A number is selected from the numbers 1 to 25
Probability of prime number which are 2, 3, 5, 7, 11, 13, 17, 19, 23 = 9
$\therefore\text{P(E)}=\frac{\text{m}}{\text{n}}=\frac{9}{25}$
$\Rightarrow\ \frac{9}{25}$
