    Answer:

    220 ways.

    Step-by-step explanation:

    This can be gotten by using the formula of combination in statistics.

    The formula for combination is given below

    nCr = n! / r!(n – r)!, where

    r = total number of object, and

    n = number of objects we’re choosing from

    Applying this to the question we have

    12C3 = 12! / 3!( 12 – 3)!

    12C3 = 12! / 3! * 9!

    12C3 = 220

    Therefore, we can choose to pack the shirts in 220 different ways
