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:
The reasonable first step would be to distribute.
Step-by-step explanation:
4x+3(x+2)=5(2x-3)
4x+3x+6=10x-15
7x+6=10x-15(subtract 7x from left side, to the right side, add 15 to the left side)
21=3x (Divide both sides by 3)
7=x
Answer:
x=7
Step-by-step explanation:
2x-10=4 add 10 to both sides
2x=14 divide both sides by 2
x=7
