a)

b)

c)

d)

Step-by-step explanation:

(a) Compute the probability that a randomly selected person does not have a birthday on October 3

if p = Probability that a randomly selected person has a birthday on October 3, then

the probability that a randomly selected person does not have a birthday on October 3 = 1-p

There are 365 days in a year, therefore p=

then 1-p=

(b) Compute the probability that a randomly selected person does not have a birthday on the 4th day of a month.

similarly, if p = Probability that a randomly selected person has a birthday on the 4th day of a month, then

Probability that a randomly selected person does not have a birthday on the 4th day of a month is 1-p

Since a year has 12 months,

p =

1-p=

(c) Compute the probability that a randomly selected person does not have a birthday on the 31st day of a month

p=probability that a randomly selected person has a birthday on the 31st day of a month

1-p =probability that a randomly selected person does not have a birthday on the 31st day of a month

Since a year has 7 months having 31 day,

p=

1-p=

(d) Compute the probability that a randomly selected person was not born in March

p= the probability that a randomly selected person was born in March

1-p = the probability that a randomly selected person was not born in March

Since March has 31 days,

p=

1-p=
