Answer:
A.
Step-by-step explanation:
Answer:
6 vans and 6 buses
Step-by-step explanation:
v+b=12 this equation represents the amount of vehicles
6v + 55b = 366 this equation represents the amount of students per vehicle.
after solving you get v=6 and b=6
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.
I am finding the answer right now but there is a website that you can use for math that really helps. It's called Desmos.
