Answer:
Number of leaves = 56
Step-by-step explanation:
Number of shirts to be chosen = 2
Number of tie to be chosen = 7
Number of jackets to be chosen = 4
We need to find the number of leaves if a tree diagram is made by using the above given information.
When making a tree diagram :
Number of shirts chosen = 2
⇒ Number of leaves = 2
Now, choosing one of 7 ties
⇒ Number of leaves = 2 × 7
Then choosing one of 4 jackets
⇒ Number of leaves = ( 2 × 7 ) × 4
Therefore, Total number of leaves in the tree diagram = ( 2 × 7 ) × 4
= 56
Thus, Number of leaves = 56
