Joey has a playlist that he listens to on his walk to school each morning. The songs are played at random, and none of the songs

ryzh [129]

Answer:

0.1515 = 15.15% probability that the first two songs that play are both country songs

Step-by-step explanation:

Songs are not repeated, which means that they are chosen without replacement, and the hypergeometric distribution is used.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

His playlist contains 5 country songs, 3 alternative songs, and 4 hip-hop songs. What is the probability that the first two songs that play are both country songs?

5 + 3 + 4 = 12 total musics, which means that $N = 12$

5 country, which means that $k = 5$

First two, which means that $n = 2$

The probability is P(X = 2). So

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,12,2,5) = \frac{C_{5,2}*C_{7,0}}{C_{12,2}} = 0.1515$

0.1515 = 15.15% probability that the first two songs that play are both country songs

9/20 divided by 4/15 fraction

Sati [7]

When you are dividing fractions, you usually flip the numerator and denominator of the second fraction and multiply. You would eventually end up with 9/20 times 15/4. You would get 135/80 and simplify if possible.
