Answer:
5% probability neither truck is available
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that the first truck is available.
B is the probability that the second truck is available.
We have that:
In which a is the probability that the first truck is available and the second one is not is the probability that both trucks are available.
By the same logic, we have that:
The probability that both trucks are available is .30.
This means that
The probability the second truck is available is .50
This means that . So
The probability the first truck is available is .75
This means that . So
The probability that at least one truck is available is:
The probability that neither truck is available is:
5% probability neither truck is available
Answer:
Given sequence is an arithmetic sequence.
Step-by-step explanation:
Given sequence is:
125, 25, 5, .. ..
Here
- A sequence is geometric sequence when the common ratio of consecutive terms is same. It is denoted by r.
- A sequence is an arithmetic sequence when the common difference of consecutive terms is same. It is denoted by d.
Finding the common ratio
As we can see that the common ratio is same, the given sequence is a geometric sequence.
