A family has two children. When asked if he has at least one daughter named Ann, the fatherreplies, "Yes." What is the probabili
Leviafan [203]

Answer:

33.3% probability that both children are girls, if we know that the family has at least one daughter named Ann.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The family has two children.

The sample space, that is, the genders of the children may be divided in the following way, in which b means boy and g means girl.

b - b

b - g

g - b

g - g

We know that they have at least one girl. So the sample space is:

b - g

g - b

g - g

What is the probability that both children are girls, if we know that the family has at least one daughter named Ann?

Desired outcomes:

Both children being girls, so

g - g

1 desired outcome

Total outcomes

b - g

g - b

g - g

3 total outcomes

Probability

1/3 = 0.333

33.3% probability that both children are girls, if we know that the family has at least one daughter named Ann.

Write negations for each of the following statements. (Assume that all variables represent fixed quantities or entities, as appr
amm1812

Answer:

a. P is a square and P is not a rectangle

b. Today is New Year’s Eve and tomorrow is not January.

c. The decimal expansion of r is terminating and r is not rational.

d. n is prime and either n is not odd or n is not 2.

e. x is nonnegative and either x is not positive or x is not 0.

f. Tom is Ann’s father and either Jim is not her uncle or Sue is not her aunt.

g. n is divisible by 6 and either n is not divisible by 2 or n is not divisible by 3.

Step-by-step explanation:

The general formula for negations that will be applied is:

Statement: If x is y, then x is z

Negation: x is y and x is not z

Statement: If x is y, then x is z and w

Negation: x is y and either x is not z or x is not w

Applying those principles:

a. P is a square and P is not a rectangle

b. Today is New Year’s Eve and tomorrow is not January.

c. The decimal expansion of r is terminating and r is not rational.

d. n is prime and either n is not odd or n is not 2.

e. x is nonnegative and either x is not positive or x is not 0.

f. Tom is Ann’s father and either Jim is not her uncle or Sue is not her aunt.

g. n is divisible by 6 and either n is not divisible by 2 or n is not divisible by 3.
