Answer:
Step-by-step explanation:
Given that one of the wagers in the game of roulette is to place a bet that the ball will land on a black number.
Probability will be 18/38 for black and red and 2/38 for green
We have
Colour Black Red Green Total
Number 18 18 2 38
Bet amt. 7 7 7
Win amt. 7 0 0
Net win 0 -7 -7
Prob 18/38 18/38 2/38
Netwin*p 0 -126/38 -14/38
Expected value of win = -140/38 = -3.68
9514 1404 393
Answer:

Answer: Because of gaps between the vertex of Pentagons and hexagon.
Step-by-step explanation:
The Pentagon has 5 sides and 5 vertex angles. While hexagon has 6 sides and six vertex angles
The sum of the angle of polygon is equal to ( n - 2 )180
Sum of the angle of a Pentagon will be: (5 - 2)×180 = 540
Each vertex angle of a Pentagon = 540/5 = 108
Sum of the angle of hexagon will be: (6 - 2)×180 = 720
Each vertex angle of a hexagon =
720/6 = 120
To interlock Pentagon and hexagon, the sum of the combination of vertex angles of both must be equal to 360 ( sum of the angles at a point = 360)
Since there is no number of combinations that can be equal to 360, there will surely be a gap.
