A drama club made $3,200 from a school play. Seventy-five percent of that amount came from ticket sales. Identify the values of
NISA [10]

Answer:

75%

Step-by-step explanation:

For this case, the first thing we will do is name variables:

a: percentage from ticket sales

b: ticket sales

We have then:

a = 75%

b = (0.75) * (3200) = $ 2400

Answer:

a = 75%

b = (0.75) * (3200) = $ 2400

The amount of ticket sales is $ 2400.

In a school in Florida, 60% of the students stay in the school's dormitory and 40% stay with their families. The school records
aivan3 [116]
We have events:

D - a <span>student stays in the school's dormitory
D' - </span>a <span>student stays with family
A - </span><span>a student receives As

and </span> probabilities:

P(D)=0.6\\\\P(D')=0.4\\\\P(A|D)=0.3\\\\P(A|D')=0.2

We want to calculate the probability <span>that the student lives in the school dormitory given he </span><span>receives As so it will be </span>P(D|A). From the <span>Bayes' theorem we know that:

P(D|A)=\dfrac{P(A|D)P(D)}{P(A)}

The only thing we don't know is P(A), but we can calculate it using the l</span><span>aw of total probability. There will be:

P(A)=P(A|D)P(D)+P(A|D')P(D')=0.3\cdot0.6+0.2\cdot0.4=\\\\=0.18+0.08=\boxed{0.26}

So our probability:

P(D|A)=\dfrac{P(A|D)P(D)}{P(A)}=\dfrac{0.3\cdot0.6}{0.26}=\dfrac{0.18}{0.26}=\boxed{\frac{9}{13}}

Answer D.
