When picking 4 Skittles, find the probability that you will pick at least one that is red.
Remember: 'at least one' means you need to use the complement of 'none' in your calculations.
You already calculated 'none red' in #12.
P(at least one red out of 4 Skittles)= 1 - P(none red out of 4 Skittles)
Round to three places past the decimal point before turning into a percent.
