In the United States, 51% of all children get an allowance and 34% of all children get an allowance and do household chores. Wha

Kobotan [32]

The conditional probability of event B happening given that event A happened is given by:

$P(B\vert A)=\frac{P(A\cap B)}{P(A)}$

Let A be the event "children get allowance and let B be the event "children do houshold chores". From the information given we have that:

$P(A)=.51$

and

$P(A\cap B)=.34$

Then the probability that a child does household chores given that it gets allowance is:

$\begin{gathered} P(B\vert A)=\frac{.34}{.51} \\ =0.6667 \end{gathered}$

Therefore the probability 66.67%

Find the TWO integers whos product is -12 and whose sum is 1<br>

Deffense [45]

Answer:

$\rm Numbers = 4 \ and \ -3.$

Step-by-step explanation:

Given :-

The sum of two numbers is 1 .

The product of the nos . is 12 .

And we need to find out the numbers. So let us take ,

First number be x

Second number be 1-x .

According to first condition :-

$\rm\implies 1st \ number * 2nd \ number= -12\\\\\rm\implies x(1-x)=-12\\\\\rm\implies x - x^2=-12\\\\\rm\implies x^2-x-12=0\\\\\rm\implies x^2-4x+3x-12=0\\\\\rm\implies x(x-4)+3(x-4)=0\\\\\rm\implies (x-4)(x+3)=0\\\\\rm\implies\boxed{\red{\rm x = 4 , -3 }}$

Hence the numbers are 4 and -3
