Answer:
0.1732 = 17.32% probability exactly 24 residents own a home.
Step-by-step explanation:
For each resident, there are only two possible outcomes. Either they own a home, or they do not. The probability of a resident owning a home is independent of any other resident. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
78% of residents in Summerville own a home.
This means that 
30 residents are randomly selected:
This means that 
Find the probability exactly 24 residents own a home.
This is P(X = 24).
0.1732 = 17.32% probability exactly 24 residents own a home.

Answer:
The answer to your question is P(chicken) = 0.30
Step-by-step explanation:
Data
number of pigs = 6
number of chickens = 7
number of cows = 10
P(chicken) = ?
Process
1.- Sum up all the number of animals
Total animals = 6 + 7 + 10
= 23
2.- Calculate the probability
P(chicken) = number of chicken / total number of animals
-Substitution
P(chicken) = 7/23
-Simplification
P(chicken) = 0.30
Answer:
$2.5
Step-by-step explanation:
4 people went to the movies and spent $ 38 ( 9.50* 4= 38) since 48-38 = 10
they totally have 10 dollars left. 10/4 = 2.5 They each $2.5 left
Answer:
B) 9
Step-by-step explanation:
I mean 3 can't be a common denominator because 2/9 cannot be simplified. 27 and 63 are also common denominators but they higher than 9.
Hope This helps :)
