dybincka [34]
The probability of two independant events P_a and P_b can be found by multiplying the individual probabilities like so:
P_t=P_{a}*P_b

For each individual probability we can find the answer via a simplfied representation: 
P_x = \frac{wanted}{total}

For the first skittle (red) we have:
P_{red} = \frac{red}{total}=\frac{5}{10}=0.5

For the second skittle (orange) we have:
P_{orange} = \frac{2}{9} = 0.2222...
**(Notice that the total is now NINE since we didn't put the first red one back in the bag.)

So:
P_{total} = P_{red} \times P_{orange}
P_{total} = \frac{5}{10} \times \frac{2}{9}
P_{total} = \frac{10}{90}=\frac{1}{9} \approx 0.1111 \approx 11.11\%
