Answer:
Step-by-step explanation:
Given that:
To bet $5 that the outcome is any one of these five possibilities: 0, 00, 1, 2, 3.
Let Y represent the Amount of net profit
Then, Y= {-5, 30}
The probability distribution of Y is:
Y -5 30
P(Y=y) 
a) The expected value of X is given by:
![E[Y] =\sum y P(Y=y)= 30*\dfrac{5}{38}-5*\dfrac{33}{38}](https://tex.z-dn.net/?f=E%5BY%5D%20%3D%5Csum%20y%20P%28Y%3Dy%29%3D%2030%2A%5Cdfrac%7B5%7D%7B38%7D-5%2A%5Cdfrac%7B33%7D%7B38%7D)
b)
On a bet of $5 on the number 25 we are expected to loose 24 cents.
While on a $5 bet that the outcome is any one of the numbers 0,00, or 1 we are expected to loose 39 cents.
Hence, $5 bet on the number 27 is better. Because the expected loss is less in this bet

Answer:
Therefore the THREE roots are
Step-by-step explanation:
Given:
To Find:
All the Roots = ?
Solution:
As the degree of the polynomial is THREE then the number of root are also THREE.
Now one root is Zero For other we need to Factorize
So by Splitting the middle term
i.e Factor of 12 such that sum should be 7
i.e 3 × 4 = 12 and 3 + 4 = 7
∴ 
Therefore the THREE roots are
