To determine which statement is best described as "certain," we need to examine the likelihood of each statement occurring.
A. You roll a standard six-sided number cube and get a value other than 1.
- The possible outcomes when rolling the die are 1, 2, 3, 4, 5, and 6. There are 5 outcomes that are values other than 1 (2, 3, 4, 5, 6) out of 6 possible outcomes. Therefore, it is likely but not certain to get a value other than 1.
B. A man drives a car 2,302 miles in 1 hour.
- This statement is not realistically possible given typical vehicle speeds. Thus, this statement is certainly false.
C. You flip a coin and get a head or a tail.
- A coin has two sides, heads and tails. When you flip a coin, you will definitely get either heads or tails, and there are no other options. Therefore, this statement is certain.
D. The next baby born at a hospital is a boy.
- The gender of babies is probabilistic and not certain. While there may be a roughly equal probability for boys and girls, it is not guaranteed that the next baby will be a boy.
Based on these evaluations:
- C. You flip a coin and get a head or a tail is the statement with likelihood best described as "certain." This is because the outcome of flipping a coin always results in either a head or a tail, with no other possible outcomes.
