Answer:
5/9
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability of not picking orange = total marbles that are not orange / total number of marbles
total marbles that are not orange = 7 +3 = 10
10 / 18
To transform to the simplest form. divide both the numerator and the denominator by 2
= 5/9
Angle x is 114 since the two are supplementary angles they always add up to 180!
Answer:
A) -$3.16; B) A $15 on the number 34
Step-by-step explanation:
To find the expected value, we multiply the probability of winning by the amount won, multiply the probability of losing by the amount lost, and add the two.
The probability of winning is 5/38 and the net profit will be $75:
5/38(75) = 375/38 ≈ $9.87
The probability of losing is 33/38 and the amount lost will be $15:
33/38(-15) = -495/38 ≈ -$13.03
We now add these amounts:
9.87+-13.03 = -3.16
Since the expected value on a single number is -$0.79 and the expected value on any one of the given numbers in the set is -$3.16, the safer bet would be on the number 34.
The answer is (A) 15.
(6x -10) makes 80 and (6x+10) makes 100
together that equales 180 degrees. since it is a straight line the sum of the the two would have to equal 180. hope this helped :D
