Final Answer:
a) 25%: Probability is 0.25
b) 45%: Probability is 0.45
c) 60%: Probability is 0.6
d) 75%: Probability is 0.75
Step-by-step explanation:
Probability is a measure of the likelihood that an event will occur. It is a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. To calculate the probability that a certain percentage of a sample is overweight or obese, it is necessary to first determine the total number of people in the sample. This number is referred to as the 'sample size'. Once the sample size is known, the probability can be calculated by dividing the number of overweight or obese people in the sample by the sample size. For example, if the sample size is 100 and 25 of those people are overweight or obese, the probability that 25% or more of the sample are overweight or obese is 0.25. Similarly, the probability that 45% or more are overweight or obese is 0.45, the probability that 60% or more are overweight or obese is 0.6, and the probability that 75% or more are overweight or obese is 0.75.
In summary, when calculating the probability that a certain percentage of a sample is overweight or obese, the probability can be determined by dividing the number of overweight or obese people in the sample by the sample size. For example, if 25 of 100 people in the sample are overweight or obese, the probability that 25% or more of the sample are overweight or obese is 0.25.
