The probability of two independant events

and

can be found by multiplying the individual probabilities like so:

For each individual probability we can find the answer via a simplfied representation:

For the first skittle (red) we have:

For the second skittle (orange) we have:
**(Notice that the total is now NINE since we didn't put the first red one back in the bag.)
