Step-by-step explanation:
The mean of a data set is the average of the data set. It can be found by adding up all of the values and then dividing by the total number of values added. In this case, one is given the mean, and one needs to find a missing value. Since there is a missing element, add one to the total number of values in the data set. The missing element is represented by the parameter (x). Set up an equation and solve:

Simplify,

Inverse operations,

60.75%. Set up a proportion equation with 243 over 400 and x over 100. Then, cross multiply and devide.
Answer:
There were 20 tables reserved. 1/10 is equivalent to 10%. To find 10%, divide the total number of tables by 10. 200/10 = 20.

Step-by-step explanation:
Since we have given that
Number of days in a year = 365
Number of students = 50
Probability that no two students share the same birthday. It means each student has different birthday.
Probability(no two students share the same birthday)
Probability(no two students share the same birthday)
Probability(no two students share the same birthday)
Probability that at least one of the students has the same birthday as another student in the class is given by
