Answer:
1/25
Step-by-step explanation:
2/10 for n
2/10 for d
2/10 times 2/10 equals 4/100
which simplifies to
The required probability is [tex]\dfrac{1}{25}[/tex]. So, option A is correct.
Important information:
- A box contains all the letters of the word UNDERSTAND.
Probability:
The number of N's is 2 and the number of D's is 2.
Total number of letters is 10.
Probablity of getting 'N' in first place is [tex]\dfrac{2}{10}=\dfrac{1}{5}[/tex].
The first letter is replaced.
Probablity of getting 'D' in second place is [tex]\dfrac{2}{10}=\dfrac{1}{5}[/tex].
Now, the probability of selecting an 'N' first and a 'D' next is:
[tex]\dfrac{1}{5}\times \dfrac{1}{5}=\dfrac{1}{25}[/tex]
Therefore, the correct option is A.
