Question

The probability that lexie is on time for a given class is 95%. if there are 32 classes during the semester, what is the best estimate of the number of times out of 32 that lexie is on time to class?

Answer 1

To estimate the number of times Lexie is on time for class, we multiply the probability of being on time (95%) by the number of classes (32), resulting in an estimate of 30.4 times.

Step-by-step explanation:

The question asks us to estimate the number of times Lexie is on time for class, given a probability of being on time is 95% for any given class. As there are 32 classes during the semester, we calculate the expected number of times Lexie is on time by multiplying the total number of classes by the probability of being on time.

Expected number of times on time = Probability of being on time × Total number of classes

= 0.95 × 32

Therefore, the best estimate for the number of times Lexie will be on time for class is 30.4 times out of 32.
