Given:
12 visitors
Visitor # Frequency of going down a water slide
1 4
2 22
3 16
4 10
5 11
6 20
7 20
8 12
9 6
10 3
11 11
12 1
Pls. see attachment for the histogram.
Solving for X:
4x= 24 - 5z
dividing by 4 on both sides
x = 6- 5/4z
Solving for Z:
5z = 24-4x
dividing by 5 on both sides:
Z= 24/5-4/5x
-- There are 12 total bottles in the box. 8 of them are grey.
-- The probability of getting a grey bottle on the first draw is 8/12 .
-- Now there are 11 bottles left in the box, and 7 of them are grey
-- The probability of getting a grey bottle on the second draw is 7/11 .
-- The probability of both events happening is
(8/12) · (7/11) = 56/132 = 14/33 = about 42.4% (rounded)
Answer:
Not to sure if this is correct but I think it is 6: 1 : 18
