Pretty sure 6.5 because line CB and ZY are similar and you divide by 3 to make them similar so you divide line AB by 3 and you get 6.5

8 -<u> 8</u>, 16, 24, 32, 40, 48  

4 - 4, <u>8</u>, 12, 16,

So the LCM of 8 and 4 are C) 8

8 - 8, 16, <u>24</u>, 32, 40, 48

6 - 6, 12, 18,<u> 24</u>, 30

So the LCM of 8 and 6 are A) 24

8 - 8, 16, 24, 32, <u>40</u>, 48

10 - 10, 20, 30, <u>40</u>, 50

The LCM of 8 and 10 are B) 40

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.
