Answer:
False.
Event A and event B are not independent.
Step-by-step explanation:
We know that event A and event B are
A= {2,4} and B= {2,4,5}.
If the following condition satisfies then event A and event B are independent:
P( A and B)= P(A)*P(B).
Now A and B=?
A and B=A∩B= {2,4} ∩ {2,4,5}
A and B=A∩B={2,4}
The single fair die results in 6 outcomes so, the sample space will contain 6 elements.
Thus,
P(A∩B)=2/6=1/3
P(A)=2/6=1/3
P(B)=3/6=1/2
P(A)*P(B)=1/3*1/2=1/6
As,
P(A∩B)≠P(A)*P(B)
1/3≠1/6
Thus, events A and event B are dependent.
Y=cos(2x+pi) - 2
y= - cos(2x) - 2
{ Since cos(x+pi) =-cos(x)}
Answer:
y(1) = 7
y(2) = 10
y(3) = 13
Step-by-step explanation:
y = 3(1) + 4
y = 3 + 4
y = 7
y = 3(2) + 4
y = 6 + 4
y = 10
y = 3(3) + 4
y = 9 + 4
y = 13

Answer:
45
Step-by-step explanation:
Let n be the original price. Then 15.20=(1-0.24)n
0.76n=15.20
n=$20.00 as the original price of the photograph
