Answer 2

Answer:

20 possible words can be formed.

Step-by-step explanation:

As per the data given in the question,

We have,

Alphabets used = Z,P,E,L,I,N

Vowells used = I,E

So, three digit words with vowells in middle:

Let E be the middle word. Now, we have 2 places left and 5 letters to select.

So, number of ways = 5C2 = 10

Simlarly,

Let I be the middle word. Now, we have 2 places left and 5 letters to select.

So, number of ways = 5C2 = 10

Hence, Total ways= 10+10 = 20

Therefore,

20 possible words can be formed.
