A) If four babies are born in a given hospital on the
same day, what is the probability that all four will be boys?
B) if four babies are born in a given hospital on the same day,
what is the probability that 3 will be girls and 1 will be a
boy?
C) You flip a coin twice what is the probability that it lands on
heads once and tails one?
Solutions
Expert Solution
A) The probability of a baby being a boy = 1/2 = 0.5
Let 
be
the event of 
baby being a boy.
Probability that all four babies will be boys = 
= 
= 0.0625
B) Let 
be
the event of
baby being a girl.
The probability of a baby being a girl = 1/2 = 0.5
Probability that 3 will be girls and 1 will be a boy = 
= 
= 0.25
C) The probability of getting head = Probaility of getting tail = 1/2 =0.5
Let 
be
the event of
toss being head.
Let 
be
the event of
toss being a tail.
Probability that it lands on heads once and tails once =
= 
= 0.5

1.
A
pediatric nurse is studying the number of babies born at a hospital
with congenital
defects. Data shows that on the average, one baby with a
congenital
defect is born per month.
a. Find the probability that at least two babies are born
with congenital defects in one year.
b. Find the probability that exactly twelve or exactly fifteen
babies are born with congenital defect in five months.
