3,180 divided by 4 = 795!
0.25 and 1/4 are the same number.
If each one is the probability of some event,
then both events are equally likely.
Answer:
Step-by-step explanation:
<u>Given the equation: </u>
- E - weekly total, g- number of hours at gas station, t- number of hours at toy store.
<u>Substitute given values into equation and solve for the missing one:</u>
- 219.75 = 9.25g + 10.5*13
- 219.75 = 9.25g + 136.5
- 9.25g = 219.75 - 136.5
- 9.25g = 83.25
- g = 83.25/9.25
- g = 9
Sydawna works 9 hours at the gas station
Probability =
(number of different successful results) / (number of all possible results) .
Number of marbles that are not blue = 7
Number of marbles in the bag = 10
Probability that one marble drawn at random is not blue = 7/10 = 70% .
Answer:
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
What is the probability that exactly two such busses arrive within 3 minutes of each other
The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use 
This probability is P(X = 2).


There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
