Answer:
S: $0.18
T: $11.73
Step-by-step explanation:
T=tickets
S=snacks
2t+3s=24
5s=28
Divide 5 with 28.
Roughly $0.18
s=0.18.
2t+3(0.18)=24
2t+0.54=24
Subtract 0.54:
2t+0.54-0.54=24-0.54
2t=23.46
Divide 2:
t=11.73
So A snack is $0.18, and a ticket is $11.73
Hope this helped!
Answer:
1170
Step-by-step explanation:
195000 * 0.006= 1170
if events X and Y are independent, then for intersection we multiply the probability
P(Y∩X) = P(Y) * P(X)
We know that

Now we replace P(Y) * P(X) for P(Y∩X)

Cancel out P(X)
So 
Like that

Now we replace P(X) * P(Y) for P(X∩Y)

Cancel out P(Y)
So 
P(Y | X) = P(Y) and P(X | Y) = P(X) are true
