<h2>Answer:</h2>

The probability that he chooses 2 oranges is:

                \dfrac{5}{14}

<h2>Step-by-step explanation:</h2>

The odds of choosing a orange from a basket is:

                           \dfrac{5}{3}

If  O denote orange

and T denote the total number of fruits

Then the odds of selecting an orange is given by:

 \dfrac{O}{T-0}=\dfrac{5}{3}

This means that:

The total number of fruits in basket i.e. T=8

so that the ratio matches.

Hence, the probability of getting orange in first draw= 5/8

Now , the second draw is independent of first and the fruits are not replaced.

This means now we have to choose fruits from remaining 7 fruits in the basket .

Probability of getting orange in second draw is: 4/7

Hence, the probability of choosing 2 oranges if the fruits are not replaced is:

  =\dfrac{5}{8}\times \dfrac{4}{7}\\\\\\=\dfrac{5}{14}

4 ∈ {4, 14, 17} is this true or false
Natalija [7]
The symbol "<span>∈" means "belongs to".
This means that a certain element belongs to or is found in the set.

The set given contains three numbers which are 4, 14 and 17.
As you can see, 4 is found in this set, therefore, 4 belongs to this set.

Based on this, the given statement is true.</span>

Answer:

Only C is a function

Step-by-step explanation:

To test whether a graph is a function you use the vertical line test.

If you can place a vertical line anywhere on the plane (in the domain of the "function" to be tested) and it intersects the curve at more than one point, the curve is not a function.

We see with A, wherever we put the vertical line it intersects twice.

With B, it intersects infinitely many times.

C is a function because wherever we put the vertical line, it only intersects once.

D is a function because it intersects twice providing we do not put it on the "tip" of the parabola.

The mathematical reasoning behind this is that a function must be well-defined, that is it must send every x-value to one specific y-value. There can be no confusion about where the function's input is going. If you look at graph B and I ask you what is f(3)? Is it 1? 2? 3? ... Who knows, it's not well-defined and so it's not a function. However if I ask you about C, whichever input value for x I give you, you can tell me to which y-value it gets mapped/sent to.
