Purple Argyle Sweater Day: A Story Problem
So, what are the chances that three teachers in the same school actually own V-neck argyle sweaters with a pattern in some shade of purple?
And how likely is it that all three of them will be English teachers?
And what, exactly, is the probability that all three of them will accidentally wear their purple argyle sweaters on the same day?
Round your answer to the nearest tenth.
