Short Answer

A certain type of dog can have long hair, medium hair, or short hair. For any length of hair, the dog can be white, grey, yellow, or brindle. Let $E _ { L } , E _ { M } , E _ { H }$ be the events of long hair, medium hair, and short hair, respectively. Let $C _ { W } , C _ { G } , C _ { Y } , C _ { B }$ be the events that a dog is white, grey, yellow, or brindle respectively. Denote $D _ { a , b } = E _ { a } C _ { b } \text { for } a \in \{ L , M , H \} , b \in$ $\{ W , G , Y , B \}$ Give a partition of this breed of dogs into 6 sets.
