If A denotes some event, what does Ā denote?
If P(A) = 0.992, what is the value of P(Ā)?
Answer :
A denotes some event , Ā denotes the complement of A that is Ā contains all the events that does not occur in A.
Given: P(A) = 0.992
We know total probability =1
P(A) + P(Ā)= 1
P(Ā)= 1 - P(A)
P(Ā)= 1 - 0.992 = 0.008
P(Ā) = 0.008
Answer:
Per child admission costs $8.5
Per Adult admission costs $13.5
Step-by-step explanation:
Let x be the amount of admission per child and y be the amount of admission per adult
For Tom's party:
13x+2y=137.50 (Equation 1)
For Lisa's Party:
9x+2y=105.50 (Equation 2)
Using Elimination Method:
Add Equation 1 & 2
13x+2y=137.50
9x+2y=105.50
- - = - (Change of Signs)
---------------------------------
4x+0y=34.00
x=34/4
x=8.5
Putting the value of x in Equation 2
13(8.5)+2y=137.50
110.5+2y=137.50
2y=137.50-110.50
2y=27
y=27/2
y=13.5
