Answer:
The total number of possible sets is 125,000,000.
Step-by-step explanation:
3 batches of plastic tumblers are red batch, yellow batch, and purple batch.
There are 500 tumblers in each batch.
We need to make a set 3 tumblers that contain 1 tumbler of each color.
The possible ways to select r items from total n items is
![^nC_r=(n!)/(r!(n-r)!)](https://img.qammunity.org/2019/formulas/mathematics/high-school/kddi54w73w8pxyq9lqu7wn2utdo6jitjuv.png)
The possible ways to select 1 red tumbler from 500 tumblers red is
![^(500)C_(1)=(500!)/(1!(500-1)!)=(500* 499!)/(499!)=500](https://img.qammunity.org/2019/formulas/mathematics/middle-school/6swa3f4zslybx7wh0me54jl7lprqq5iq0k.png)
The possible ways to select 1 yellow tumbler from 500 tumblers yellow is
![^(500)C_(1)=(500!)/(1!(500-1)!)=(500* 499!)/(499!)=500](https://img.qammunity.org/2019/formulas/mathematics/middle-school/6swa3f4zslybx7wh0me54jl7lprqq5iq0k.png)
The possible ways to select 1 purple tumbler from 500 tumblers purple is
![^(500)C_(1)=(500!)/(1!(500-1)!)=(500* 499!)/(499!)=500](https://img.qammunity.org/2019/formulas/mathematics/middle-school/6swa3f4zslybx7wh0me54jl7lprqq5iq0k.png)
Total possible ways to make a set of 3 tumblers that contain 1 tumbler of each color are
![500* 500* 500=125000000](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ent5kxsk4lntp9pf7ojq5f41rploya8r4n.png)
Therefore the total number of possible sets is 125,000,000.
