deb spins this spinner once. which tree diagram represents the sample space of this event?
Answer
Answer:
The third tree - diagram (from the top - left, it is the one with three branches labeled 1, one labeled 2, one labeled 3 and one labeled 4).
Explanation:
Step1: Identify possible outcomes
The spinner has three sections labeled 1, one section labeled 2, one section labeled 3 and one section labeled 4.
Step2: Match with tree - diagram
The tree - diagram should have three branches for 1, one for 2, one for 3 and one for 4 to represent the sample space. The third tree - diagram satisfies this.
