Answer:
Step-by-step explanation:
Given: A bushel contains 4 pecks and a peck contains 8 quarts.
i.e. A bush = 4 pecks
A peck = 8 quarts
Then, Number of quarts in 1 bush = 4 (8) =32
Let b = number of bushes and q = number of quarts
Number of quarts(q) in b bushes = 32b
hence, required equation: which describes the relationship between the number of b bushels and the number of q quarts.
Answer:
The probability is
Step-by-step explanation:
If she has n distinct password candidates and only one of which will successfully log her into a secure system, the probability that her first first successful login will be on her k-th try is:
If k=1
Because, in her first try she has n possibles options and just one give her a successful login.
If k=2
Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and 1 of that give her a successful login.
If k=3
Because, in her first try she has n possibles options and n-1 that are not correct, then, she has n-1 possibles options and n-2 that are not correct and after that, she has n-2 possibles options and 1 give her a successful login.
Finally, no matter what is the value of k, the probability that her first successful login will be (exactly) on her k-th try is 1/n
