$5800 at 9%
$1200 at 11%

0.09(x) = interest earned at 9%
0.11(7000-x) = interest earned at 11%

0.09(x) + 0.11($7000-x) = $654
0.09x + $770 - 0.11x = $654
$770 - $654 = 0.11x - 0.09x
$116 = 0.02x
$116/0.02 = x
$5800 = x

$5800 * 0.09 = $522

($7000-$5800) * 0.11 = $132

A students' choir contains 25 children and only 5 of them play the piano. If a child is selected at random, what is the probabil
solniwko [45]

Answer:

probability that the child DOES NOT play the piano

P(E^{-})  =\frac{4}{5}

Step-by-step explanation:

A students' choir contains 25 children

n(S) =25

The number of students play the piano =5

Let 'E' be the event of the child play the piano so n(E) =5

The probability of that the child play the piano

 P(E) = \frac{n(E)}{n(S)}

 P(E) = \frac{5}{25}= \frac{1}{5}

Let 'E⁻ be the event of the child play does not play the piano

P(E^{-}) = 1- P(E)

P(E^{-}) = 1- \frac{1}{5} =\frac{4}{5}

<u>Conclusion</u>:-

probability that the child DOES NOT play the piano

P(E^{-})  =\frac{4}{5}
