Answer 2

Answer:

The ways in which number of 6 digits can be formed is given by 38880.

Step-by-step explanation:

Given : Of 6 digit number that can be formed from 0 1 5 6 7 and 8 in which the first digit is not  0.

To find : The number of ways number can form.

Solution :

We have been given 0,1,5,6,7,8.

We have to make a 6 digit number.

0 can't be at the first place (from left to right).

Hence, there will be 5 ways to fill the first place.

$6\times 6\times 6\times 6\times 6=6^5$

Number of ways to fill first blank is $6^5=7776$

In the remaining places we can place any digits.

So in remaining 5 places, we have

$5\times 7776=38880$

Therefore, the ways in which number of 6 digits can be formed is given by 38880.
