<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}

"Rebecca walks 100 feet in a straight line. She then turns 20 degrees to her left and walks another 100 feet, and then turns 20
iragen [17]

Answer:

1,800 ft

Step-by-step explanation:

Rebecca will walk in the pattern of a regular polygon with 'n' sides and internal angles of 160 degrees (180 at a straight line - 20 degrees from each turn).

The equation that describes the internal angle of a regular polygon is:

A = \frac{(n-2)*180}{n}

For A = 160 degrees:

160n=(n-2)*180\\(180-160)n=360\\n=18\ sides

If each side is 100 ft long, the total distance that Rebecca has walked is:

d = 18*100\\d=1,800\ ft

She walked 1,800 ft.
