So if you just use a calculator and put 375 divided by 30% you’ll get the answer but the answer is 0
Answer:
289/290
Step-by-step explanation:
Given that the chance of Donnell being selected is 1/290
then P( Donnell being selected )= 1/290
Since Donnell and Maria are both member of a population.
from probability theorem which gives the likely hood of an event to happen which cannot be more than 1, then the probability of Donnell and Maria to be selected is 1
P(Donnell and Maria)= 1
But the chance of Donnell being selected is 1/290
Then,
1/290 + P(Maria)= 1
P(Maria)= 1-(1/290)
= 289/290
the chance of Maria being selected is 289/290
Answer: 5 and 7.
Step-by-step explanation: I’m sorry I don’t know what kind of equation to do but I’ll show how I got the answer if that’s what you mean.
First I made a list of numbers that when multiplied equal 35
Then I went through the list and took out all the options that were not one number being 2 more than the other.
The only option left is 5 x 7 (5*7)
what kind of equation do you want? Like 5*7 = 35 and 5 + 2 = 7?
Solution :
Given :
The events are as follows :
P : Set of all the people
S : Set of people those who are single
C : Set of people having children
W : Set of women
M : Set of men
a). Now set of married women having children is given by :
![$\left( (P-S)-M \right) \cap C $](https://tex.z-dn.net/?f=%24%5Cleft%28%20%28P-S%29-M%20%5Cright%29%20%5Ccap%20C%20%24)
And set of single women who do not have any children : (S -C) - M
Thus the set of women those who are either married and have children or they are single and they do not have any children is represented by :
![$\left( (S-C)-M\right) \cup \left( ((P-S)-M) \cap C \right) $](https://tex.z-dn.net/?f=%24%5Cleft%28%20%28S-C%29-M%5Cright%29%20%5Ccup%20%5Cleft%28%20%28%28P-S%29-M%29%20%5Ccap%20C%20%5Cright%29%20%24)
b). Set of Married men : ![$\left( (P-S) \cap M$](https://tex.z-dn.net/?f=%24%5Cleft%28%20%28P-S%29%20%5Ccap%20M%24)
Set of Married men : ![$\left( (P-S) \cap W$](https://tex.z-dn.net/?f=%24%5Cleft%28%20%28P-S%29%20%5Ccap%20W%24)
Set of all possible married who are heterosexual couples, that is, all possible pairings of the married men and the married women is represented by :
![$((P-S) \cap M) \cap ((P-S) \cap W )$](https://tex.z-dn.net/?f=%24%28%28P-S%29%20%5Ccap%20M%29%20%5Ccap%20%28%28P-S%29%20%5Ccap%20W%20%29%24)
c). The number of all the possible married heterosexual couples will be represented by the cardinality of the above set, which represents the number of the elements in the set.
Thus the number of the married heterosexual couples is given by :
![$n[((P-S) \cap M) \cap ((P-S) \cap W)]$](https://tex.z-dn.net/?f=%24n%5B%28%28P-S%29%20%5Ccap%20M%29%20%5Ccap%20%28%28P-S%29%20%5Ccap%20W%29%5D%24)
We need a picture please, we cannot see the triangle
