6 Answers

it got to be 1/2

correct again priyam method plz

there are two elements is sample space even or odd and fav is even thats why 1/2

if a six digit no is selected at random its sum should be odd or even no

therefore required prob=
n(favourable outcomes)/n(elements in samplespace)

got it guyz
