Adult ticket costs= $46
Children ticket costs= $104
Let x represent the price of adult tickets
Let y represent the price of children tickets
x + y= 150.......equation 1
8x + 3y= 970........equation 2
From equation 1
x= 150 - y
substitute 150-y for x in equation 2
8(150-y) + 3y= 970
1200- 8y + 3y= 970
-8y + 3y= 970-1200
-5y= -230
y= 230/5
y= 46
From equation 1
x + y= 150
x + 46= 150
x= 150 - 46
x= 104
Hence the cost of children tickets is $104 and the cost of adult tickets is $46

Answer:
Yes, Based on this data, baldness and being over 45 are independent events, because P(bald | over 45) = P(bald).
Step-by-step explanation:
The given data is as following:
Under 45 Over 45 Total
Bald : 24 16 40
Not Bald : 36 24 60
Total : 60 40 100
<u>We should know that:</u>
The events A and B are independent when If P(A∩B) = P(A) * Pr(B)
Using conditional probabilities this property can be written as:
P(A|B) = P(A∩B)/P(B) = P(A) * Pr(B)/ P(B) = P(A)
So, we will check baldness and being over 45 independent events.
From the given data:
1. P(man is bald) = 40/100 = 0.4
3. P(bald | over 45) = 16/40 = 0.4
So, P(man is bald) = P(bald | over 45) = 0.4
<u>So, The events are independent. </u>
