0,1,2,3,4,5,6,7,8,9 are the numbers.
1,3,5,7,9 are odd numbers.
But other than 5, so 1,3,7,9

Ans.->Zero
since the product end in odd other than 5 so the number 5 cannot be selected.
now we have 1,2,3,4,6,7,8,9 numbers to select six no.whose multiplication of each digits will produce an odd no.
out of six no.s we have to select at least 2 even no.which after multiplication will give an even no. and finally the result of the multiplication will give an even no.
so the probability of getting an odd result is zero
