Answer:

87

Step-by-step explanation:

The expected value is the product of the probability and the outcome.

E = 0.98 (89)

E = 87.22

Rounded to the nearest integer, the expected number of classes is 87.

The best estimate of the number of times out of 89 that Lexie is on time to class is 87.22.

Given that,

  • The probability that Lexie is on time for given class is 98 percent and there are 89 classes during the semester.

Based on the above information, the calculation is as follows:

[tex]= 89 \times 0.98[/tex]

= 87.22

Therefore we can conclude that The best estimate of the number of times out of 89 that Lexie is on time to class is 87.22.
