Explanation / Answer

Solution:

   17)

      Part a) We have to find the probability that a randomly selected person has his or her birthday is October 18 , which is a National statistics daya in Japan. we have to ignore leap year.
So for non leap year , there are total 365 days.

A person can born on any day of the year with equal chance for each day.

So P(a person born on any day of the year ) = 1 / 365

Thus

P( a person born on day October 18 of the year ) = 1 / 365

P( a person born on day October 18 of the year ) = 0.000274

Part b) we have to find Probability of a randomly selected person has his or her birthday in October.

Month october has 31 days , so person whose birthday in octber has 31 possitbilities.

Thus

P( a person has birthday in October) = Number of days in October / Total days in year

P( a person has birthday in October) = 31 / 365

P( a person has birthday in October) = 0.08493

Part c) We have to find the probability that a randomly selected person has his or her birthday on the day of the week that ends with letter y

All the days of the week end with letter y

That means all the days of the year has days with letter ending with ' y '.

Thus there are 365 possibilities.

Thus

P( a person has his or her birthday on the day of the week that ends with letter y) = 365 / 365

P(a person has his or her birthday on the day of the week that ends with letter y ) = 1
