Answer:

Let's see what to do buddy...

Step-by-step explanation:

first \:  \:  \:  \frac{1}{4} \:  \:  \:of \:a \: song \: needs \:  \frac{1}{8} \:  \: minute. \\  \\ second \:  \:  \:  \frac{1}{4} \:  \: of \: a \: song \: needs \:  \frac{1}{8} \: minute \: too. \\  \\ also \: the \: third \: and \: fourth \:  \:  \:  \frac{1}{4} \:  \:  \:  of  \: a \: song \: need \:  \frac{1}{8} \: minute \: . \\  \\ so \: we \: have \: completly \: have \: 4 \times  \frac{1}{8} \\  \\ which \: means \: edi \: needs \: 4 \times  \frac{1}{8}  =  \frac{4}{8} =  \frac{1}{2} \:  minute \: to \: play \: all \: the \: song.

And we're done.

Thanks for watching buddy good luck.

On a particular game show, there are 8 covered buckets and 2 of them contain a ball.
kobusy [5.1K]

Answer:

0.2143 = 21.43% probability that a contestant wins the game if he/she gets to select 4 of the buckets.

Step-by-step explanation:

The buckets are chosen without replacement, which means that the hypergeometric distribution is used to solve this question.

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)!}

In this question:

8 covered buckets, so N = 8.

4 buckets are selected, so n = 4.

2 contain a ball, which means that k = 2.

Find the probability that a contestant wins the game if he/she gets to select 4 of the buckets.

This 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(2,8,4,2) = \frac{C_{2,2}*C_{6,2}}{C_{8,2}} = 0.2143

0.2143 = 21.43% probability that a contestant wins the game if he/she gets to select 4 of the buckets.
