Answer 2

Answer:

96 even four digit numbers can be formed.

Step-by-step explanation:

Here we have 4 digits

_ _ _ _

Our options are 0,1,2,3,4,5,6,7.

Last blank can either have 0,2,4 or 6.

_ _ _ _

4

As numbers cannot be repeated we can fill the first blank with remaining 4 numbers.

_ _ _ _

4. 4

Second blank can have 3 numbers and third blank can have 2 numbers.

_ _ _ _

4 3 2 4

Thus the total number of four digit even numbers formed can be

4 x 3 x 2 x 4 = 96 .
