Final answer:
The probability cannot be calculated accurately without additional information.
Step-by-step explanation:
The probability that an individual who sleeps for more than 8 hours also sleeps for more than 10 hours can be determined by looking at the given data. However, since no data specifically mentioning the number of individuals who sleep for more than 8 hours and more than 10 hours is provided, we cannot calculate the probability accurately. We need additional information on the number of individuals who fall into both categories to compute the probability.
