-d would equal 3. just flip its around right?
The probability of one dice rolling an even number is 1/2 as half the numbers are even. Since the events are independent, and there are 2 dice, we need to square 1/2 to get 1/4, assuming they are both fair dice

convert 3.9 kg to grams
3.9×1000=3900 g
density = mass/ volume
= 3900/ 200
=19.5 g/cm3
