Given:
A fair die is rolled.
It pays off $10 for 6, $7 for a 5, $4 for a 4 and no payoff otherwise.
To find:
The expected winning for this game.
Solution:
If a die is rolled then the possible outcomes are 1, 2, 3, 4, 5, 6.
The probability of getting a 6 is:
The probability of getting a 5 is:
The probability of getting a 4 is:
The probability of getting other numbers (1,2,3) is:
We need to find the sum of product of payoff and their corresponding probabilities to find the expected winning for this game.
Therefore, the expected winnings for this game are $3.50.
The saying is "Five or above, give it a shove. Four or below, let it go" Meaning, round up if the following number is ≥5, and to round down if the number is ≤4
In this case, 80.945 would be rounded to 80.9.
Hope this helps!
Answer: Balloon is 27.5 ft high.
Step-by-step explanation:
As per the give , we made a diagram (in attachment).
To find the vertical distance from the growth we consider entire triangle as right triangle , where height is making right angle with ground.
in right triangle,
hence, balloon is 27.5 ft high.
Answer:
35
Step-by-step explanation:
3/2 · 4/3 · 5/4 · 6/5 ·…· a/b =9
a+b=?
------
all numbers get cancelled apart from the first denominator and the last numerator:
1/2*a= 9
then
a+b= 18+17= 35
Answer:
The answer is 4/3
Step-by-step explanation:
TO divide two fractions, you can flip the second one and then multiply.
2/3 ÷ 1/2
2/3 * 2/1 = 4/3
