How many six digit even numbers are possible if the leftmost digit cannot be zero

450000 six digit even numbers are possible if the leftmost digit cannot be zero.

Step-by-step explanation:

We have to find Total six digit even numbers.

To form an even of 6 digit we have 10 digits to place in first 5 position starting from left most, here repetition is allowed so, No ways of doing this is  and number of ways selecting one digit from 5 digit for ones place is [/tex]^{5}\textrm{P}_{1}=\farc{5!}{(5-1)!}=\frac{5!}{4!}=5[/tex]

So, Total even numbers =

This includes number which has zero on the left most place.

To get these numbers we fir 0 at place 2 left 4 places has 9 options and ones place has 5 options as before.

So, Number of such cases =

Thus, total Number of 6 Digit number even number = 500000 - 50000 = 450000

Therefore, 450000 six digit even numbers are possible if the leftmost digit cannot be zero.

answer:   segregation violated the equal protection clause of the 14th amendment, which holds that no state can “deny to any person within its jurisdiction the equal protection of the laws.”

the ruling was important in advancing civil rights because it affirmed that the 14th amendment applies to all rights and privileges of citizens, including access to   education.   this was being violated by states whose laws supported the segregation of schools.   section 1 of the 14th amendment reads as follows:
