Answer:
A
Step-by-step explanation:
3x 2/6 is 1 and if you put all the shaded blocks together for A, you will get 1 whole
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:
16/4
Step-by-step explanation:
<u>Step 1: Convert to improper fractions</u>
2 2/4 = 2 * 4/4 + 2/4 = 8/4 + 2/4 = 10/4
1 1/2 = 1 * 2/2 + 1/2 = 2/2 + 1/2 = 3/2
<u>Step 2: Make common denominator</u>
10/4 is ok
3/2 * 2/2 = 6/4
<u>Step 3: Combine </u>
10/4 + 6/4
16/4
Answer: 16/4
Answer:

Step-by-step explanation:
Given series is,
50,80,110....
First term, a = 50
Common difference, d = 80-50 = 30
We need to find the nth term of the given sequence.
The nth term of an AP is given by :

Put a = 50 and d = 30 in the above formula

Hence, the nth term of the sequence is
.
