Answer:
0.667 is the probability that Billy will roll a 3 or higher.
Step-by-step explanation:
We are given the following in the question:
E: Rolling of a six-sided die
The sample space for the given event is
S: {1, 2, 3, 4, 5, 6}
We have to find the probability that Billy will roll a 3 or higher.
P( roll a 3 or higher) =
![\displaystyle\frac{n(\text{ 3 or higher)}}{6} = \frac{4}{6} = \frac{2}{3} = 0.667](https://tex.z-dn.net/?f=%5Cdisplaystyle%5Cfrac%7Bn%28%5Ctext%7B%203%20or%20higher%29%7D%7D%7B6%7D%20%3D%20%5Cfrac%7B4%7D%7B6%7D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%20%3D%200.667)
Thus, 0.667 is the probability that Billy will roll a 3 or higher.

The answer should be c :)
Answer:
chance of winning $100 = 1/1000
chance of winning $50 = 5/1000 = 1/200
cost of ticket = -1
E[x] = 100* 1/1000 + 50* 1/200 -1
= 0.1 + 0.25 - 1 = -0.65

Answer:
1) 8 m^3
2) 125 + 25
3) 8
Step-by-step explanation:
1) It's a cube shape => length = width = height = 2 m
Volume = length × width × height = 2 × 2 × 2 = 8 m^3
2) 5^2 + 5^3 = 150
25 + 125 = 150
3) Now she is 8 years old (8 = 2^3)
Next year she'll be 9 years old (9 = 3^2)
