Answer:
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Step-by-step explanation:
Consider the provided information.
Machine A can fill an order of widgets in a hours. Machine B can fill the same order of widgets in b hours.
Thus, in 1 hr machine A's work is 1/a and machine B's work is 1/b.
We need to find whether the Machine A's rate the same as that of Machine B?
Statement 1: Machines A and B finish the order at exactly 4:48 p.m.
Total time, A and B worked = 4:48 = 4+ hrs = 4+
hrs=
hours
Thus,
Let say Machine A's rate the same as that of Machine B
It is given that a and b are even integers, but is not an even integer.
Hence, Machine A's rate is not same as that of Machine B.
Therefore, statement (1) ALONE is sufficient.
Statement 2:
There are many possible case in which a and b are even integer and there sum is 20.
If a = b = 10 (both even), then Machine A's rate is same as that of Machine B.
if a = 6 and b = 14 (both even), then Machine A's rate is not same as that of Machine B.
Therefore, No unique answer with statement 2.
Hence, statement 2 alone is not sufficient.
Answer:
0.182 probability that the Yankees will win when they score fewer than 5 runs
Step-by-step explanation:
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this problem:
When the Yankees score less than 5 runs, either they win, or they lose. The sum of these probabilities is 1.
Probability they lose:
Event A: Scoring fewer than 5 runs.
Event B: Losing
The probability that the Yankees will score 5 or more runs in a game is 0.56.
So 1 - 0.56 = 0.44 probability the Yankees score fewer than 5 runs.
This means that
The probability that the Yankees lose and score fewer than 5 runs is 0.36.
This means that
Then the probability they lose is:
Probability they win:
p + 0.818 = 1
p = 0.182
0.182 probability that the Yankees will win when they score fewer than 5 runs
