The expected value is the sum of the probablity of each outcome multiplied by the "value" of each outcome.
Its sort of like a special average.
In your case each outcome has probability <span>16</span></span></span>
. and you get 5 dollars when you roll 3 or 6 when you roll something else.
So the expected value is
<span><span>06</span>+<span>06</span>+<span>56</span>+<span>06</span>+<span>06</span>+<span>56</span>=<span>106</span>=<span>53</span></span>
.
This means loosely that if you played this game a lot you should
expect to win on average about 1.66 dollars, while you payed 3 to play
it. Clearly this is a great idea if you want to lose money.
Answer:
<u>45°</u>
Step-by-step explanation:
From the diagram :
- ∠AOC = ∠AOB + ∠BOC
- 96 = 9x - 75 + 8x - 67
- 17x - 142 = 96
- 17x = 238
- x = 238/17
- x = 14
Finding ∠BOC :
- ∠BOC = 8x - 67
- ∠BOC = 8(14) - 67
- ∠BOC = 112 - 67
- ∠BOC = <u>45°</u>
Answer:
=4tx2+11xy
Step-by-step explanation:
7xy−x2t+4xy+5x2t
=7xy+−tx2+4xy+5tx2
=(−tx2+5tx2)+(7xy+4xy)
=4tx2+11xy
