$\large{ \tt{❋ \: EXPLANATION}} :$

The formula to find out the volume of a rectangular prism is V = l × b × h where V is the volume , l = length , b = breadth & h = height.

We're provided the figure of trapezium in the second attachment. The formula to fInd out the area of trapezium is A = $\tt{ \frac{1}{2} h(a + b)}$ where a and b are the opposite parallel sides and h be the height of a trapezium.

$\large{ \tt{❃ \: SOLUTION}} :$

In the first picture , we're provided - Length ( l ) = $\frac{7}{4}$ cm , breadth ( b ) = $\frac{3}{2}$ cm and height ( h ) = $\frac{1}{2}$ cm. Now, plug these known values and them find out the volume of given rectangular prism.

$\large{ \tt{❁ \: VOLUME \: OF \: RECTANGULAR \: PRISM \: ( \: V \: ) = l \times b \times h}}$

$\large{ {⟶ \: \frac{7}{4} \times \frac{3}{2} \times \frac{1}{2} }}$

To multiply one fraction by another , multiply the numerators for the numerator and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term if possible.

$\large{ ⟶ \frac{7 \times 3 \times 1}{4 \times 2 \times 2} }$

$\large{⟶ \frac{21}{16} \tt{ {cm}^{3} }}$

Hence , the volume is $\boxed{ \frac{21}{16} }$ cubic centimetres.

--------------------------------

In the second attachment , we're provided - 6ft and 7 ft are the opposite parallel sides and 3 ft is the height of the given trapezium.

$\large{ \tt{✺ \: AREA \: OF \: A \: TRAPEZIUM = \frac{1}{2} h(a + b)}}$

$\large{ ⟶ \frac{1}{2} \times 3(6 + 7)}$

$\large{⟶ \: \frac{1}{2} \times 3 \times 13 }$

$\large{⟶ \frac{39}{2} \tt{cm}^{2} }$

Hence , The area of trapezium is $\boxed{ \frac{39}{2} \tt{cm}^{2} }$

And we're done ! ♪

OlgaM077 [116]

The probability that both specific qualified applicants will be among the eight selected is given by:
$P(2\ specified)=\frac{2C2\times 48C6}{50C8}=0.0229$
The probability that the two will get apartments on the North side is given by:
$P(North)=\frac{3C2\times5C0}{8C2}=0.107$
The probability that the two will get apartments on the South side is given by:
$P(South)=\frac{5C2\times3C0}{8C2}=0.357$
The events '2 apartments on North side' and '2 apartments on South side' are mutually exclusive. Therefore the probability the two specific qualified applicants will be on the same side of town is 0.107 + 0.357 = 0.464.
Finally, the probability that two specific qualified applicants will be selected for apartments on the same side of town is found from:
$0.0229\times0.464=0.01063$
