You need the probability of getting a red disk in disk 1 and then a while disk in disk two, then you need to find the probability of getting a while disk then a red disk then add them up
so 6/9 * 3/9 + 3/9 * 6/9 = P(R,W)+P(W,R)

Part B is wrong
Probability of one homework has two paths.
If maths no homework then english home work and maths homework then english no home work
or
P(H,NH) and P(NH,H)
Try it again now. Remember once you find the probability of both outcomes, you need to add them together.

I'm not sure on the units for this questions I have to find the mass. The title of this work is called compound measure.

What's 1KM?
KM usually refers to a measurement of distance (kilometres), not volume. Are you sure that's right? Can you show the question please?

You can't use the formula with density in terms of g per cm^3 and volume in km^3
How many cm in a km and therefore how many cm^3 in a km^3 - think about it before you answer

How many cm in a m
How many m in km
So how many cm in a km
Now imagine a cube that measures 1 km in each direction, how would you calculate its volume

There are 100000 cm in 1 km. So in 1cm3 there are 100000^3 in 1km3 =1015 km3.
Original post by z_o_e
You don't know that there are 100 cm in a m?
or 1000 m in 1 km?
So 100 x 1000 cm in a km

Copper- 89.62 g/cm^3 - 14700 / 164
Air - 15.38 m^3 - 20kg * 0.0013g/cm^3 then I just converted it into M^3, however it's probably easier to convert the 0.0013g/cm^3 in m^3 first.
Edit: I did hydrogen wrong.
