Which statement is true about whether Z and B are

Mathematics

Dmitrij [34]3 years ago

Answer:

Z and B are independent events because P(Z I B) = P(Z)

Step-by-step explanation:

  • If Z and B are independent, Z does not affect B and B does not affect Z.
  • This means that, to know something about B does not help predicting Z, and to know something about B does not help predicting Z.
  • Then,  the probability P (Z/B) = P(Z) because B does not add any information about Z, therefore, the probability of Z only depends on itself.

What is converse inverse and contrapostive?

<span>rhythm of the falling rain answered 6 year<span>Given an if-then statement "if p, then q", we can create three related statements: 


A conditional statement consists of two parts, a hypothesis in the “if” clause and a conclusion in the “then” clause. 

For instance, “If it rains, then they will cancel school.” 
“It rains, “is the hypothesis. 
“They will cancel school,” is the conclusion. 

To form the converse of the conditional statement, interchange the hypothesis and the conclusion. 

The converse of “If it rains, then they will cancel school.” is 
“If they cancel school, then it rains.” 

To form the inverse of the conditional statement, take the negation of both the hypothesis and the conclusion. 

The inverse of “If it rains, then they will cancel school” is “If it does not rain, then they do not cancel school.” 

To form the contrapositive of the conditional statement, interchange the hypothesis and the conclusion of the inverse statement. 

The contrapositive of “If it rains, then they will cancel school” is “If they do not cancel school, then it does not rain.” 

Summary: 
Statement If p, then q. 
Converse If q, then p. 
Inverse If not p, then not q. 
Contrapositive If not q, then not p. 

If the statement is true, then the contrapositive is also logically true. If the converse is true, then the inverse is also logically true. 

Example: 
Statement If a person is 18 years old, then he is a legal adult. 
Converse If a person is a legal adult, then he is 18 years old. 
Inverse If a person is not 18 years old, then he is not a legal adult. 
Contrapositive If a person is not a legal adult, then he is not 18 years old.</span></span>

[2] (c) Another bag contains 15 red beads and 10 yellow beads. Ariana picks a bead at random, records its colour and replaces it
zlopas [31]

Answer:

(c)

<u>Total number of beads:</u>

  • 15 + 10 = 25

(i)

<u>Probability of 2 red:</u>

  • P(RR) = 15/25*15/25 = 9/25

(ii)

<u>Probability of no 2 red:</u>

  • P(R'R') = 1 - 9/25 = 16/25

Josh is going to the store to buy cakes to share with the fifth grade. He wants to share the cakes with 86 students. He buys 35
Ipatiy [6.2K]

Answer:

Everyone will get \frac{35}{86} amount of cakes.

Step-by-step explanation:

Given:

Number of Cakes Josh buys = 35

Number of Students Josh wants to share = 86

Josh need to share cakes with fifth grade students.

We need to find the fraction of cakes everyone will get.

So to find the the fraction of cakes everyone will get can be calculated by dividing Number of Cakes Josh buys with Number of students he want to share with.

Amount of cakes Every one will get = \frac{\textrm{Number of Cakes}}{\textrm{Number of Students}}

Now Substituting the values we get;

Amount of cakes Every one will get = \frac{35}{86}

Hence Everyone will get \frac{35}{86} amount of cakes.

Write an equation to express the value of h + k
Dahasolnce [82]
So since, they are the same distance from zero, they should be the oppposite of each other so in other words, k=-h and h=-k

so k+h=(subisute)k-k=-h+h=0 because they cancel
