Alice has 4 red, 2 pink, 1 white, and 5 blue shirts in a drawer. Without looking, Alice pulled out a red shirt and put it on her bed. What is the probability Alice will pull out a blue shirt after she pulled out the red one?

The probability is 5/11 as a fraction, about 45%, and/or 0.45 as a decimal.

Probability formula: Possible values/ Favorable values

Step 1: add the possible values: 4 + 2 + 1 + 5. This is equal to 12 possible options.

Step 2: Since Alica pulled out a red shirt, there will be 11 possible options (12-1 shirt = 11 possible options)

Step 3: Since we are expecting a blue shirt and there are 5 blue shirts, there is a 5/11 chance. Hope this helps!
