Answer:
I guess they rounded, but the answer is .5000 or 50% chance
Step-by-step explanation:
Count the total chances. There is a chance it will be 10oz, 11oz, 12oz, 13oz, 14oz, 15oz, or 16oz. The question asked 13 or more. That is 13, 14, 15, and 16.
That is a 4/7 chance or probability it will be more than 13oz. Divide 4 and 7 to get your answer.
0.57 or 57%
