15% are green,
the remaining are orange.
Find the probability that you pick one orange skittle.
P(orange)=
What is the complement of picking an orange Skittle?
Select the best answer choice:
Find the probability that you will pick a red or a green skittle.
P(red or green)=
What needs to be true about choosing a Skittle in order to do the calculations for #4?
Find the probability that you will not pick a pink skittle.
P(pink)=
When picking 2 Skittles, find the probability that you will pick two purples.
P(Purple, Purple)=
Enter all decimal places for this one.

What is the probability that you will not get a purple Skittle until the fourth one selected?
P(not purple, not purple, not purple, purple)=

When picking 4 Skittles, find the probability that you will pick none that are red.
P(not red, not red, not red, not red)=
Round to three places past the decimal point before turning into a percent.
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.
