Chapter 3: Q3.16 (page 98)

Ninety-eight percent of all babies survive delivery. However, 15 percent of all births involve Cesarean (C) sections, and when a C section is performed, the baby survives 96 percent of the time when a C section is performed, the baby survives 96 percent of the time . If a randomly chosen pregnant woman does not have a C section, what is the probability that her baby survives?

Short Answer

Expert verified

The probability that a randomly chosen pregnant woman does not have a C section, is that her baby survives is 0.9835

Step by step solution

01

Given Information

Given that ninety-eight percent of all babies survive delivery.

15 percent of all births involve Cesarean (C) sections,

when a C section is performed, the baby survives 96 percent of the time

We have to find the probability that a baby survives at randomly chosen pregnant women does not have a C section,

C : Cesarian delivery,CC: Normal delivery,S: Survival,D: Death

P(S)=0.15脳0.96+0.85脳x

P(S)=0.98 given

0.98=0.15x0.96+0.85xx

鈬�x=0.9835

Ste 4  Final Answer

The probability that a randomly chosen pregnant woman does not have a C section, is that her baby survives is 0.9835

A and B play a series of games. Each game is independently won by A with probability p and by B with probability 1鈭� p. They stop when the total number of wins of one of the players is two greater than that of the other player. The player with the greater number of total wins is declared the winner of the series.

(a) Find the probability that a total of 4games are played.

(b) Find the probability that A is the winner of the series

Show that if P(A)>0, then

P(AB鈭�A)鈮�P(AB鈭�A鈭�B)

In a certain village, it is traditional for the eldest son (or the older son in a two-son family) and his wife to be responsible for taking care of his parents as they age. In recent years, however, the women of this village, not wanting that responsibility, have not looked favorably upon marrying an eldest son.

(a) If every family in the village has two children, what proportion of all sons are older sons?

(b) If every family in the village has three children, what proportion of all sons are eldest sons?

Assume that each child is, independently, equally likely to be either a boy or a girl.

An urn contains 12 balls, of which 4 are white. Three players A, B, and C successively draw from the urn, A first, then B, then C, then A, and so on. The winner is the

first one to draw a white ball. Find the probability of winning

for each player if

(a) each ball is replaced after it is drawn;

(b) the balls that are withdrawn are not replaced.

Suppose that an ordinary deck of 52 cards (which contains 4 aces) is randomly divided into 4 hands of 13 cards each. We are interested in determining p, the probability that each hand has an ace. Let Ei be the event that I the hand has exactly one ace. Determine p = P(E1E2E3E4) by using the multiplication rule.
