Answer:
11/4 or , 2 3/4
Step-by-step explanation:
I don't like math so I am not going to call it fun, but these problems are super easy for me, so it almost IS fun.
4/4 = 2/2 because they are both wholes.
2/4 = 1/2 because they are both halves.
Now, if we split one of the numbers down, we will get one of these.
6 1/4
6 x 4 because there are 6 wholes...= 24
then 24 plus 1 because there is still one fourth...=25
25/4
Now, 3 1/2 pounds.
Lets change it to fourths. 3 2/4
Now, 3 x 4, 12, then 12 plus 2 equals 14/4
Now compare your numbers.
The answer to that is 128.18

Answer:
C) r= C/ 2π
Step-by-step explanation:
C=2πr
C/2=πr
C/2π=r
Conditional probability is a measure of the probability of an event given that another event has occurred. If the event of interest is A and the event B is known or assumed to have occurred, "the conditional probability of A given B", or "the probability of A under the condition B", is usually written as P(A|B), or sometimes

.
The conditional probability of event A happening, given that event B has happened, written as P(A|B) is given by

In the question, we were told that there are three randomly selected coins which can be a nickel, a dime or a quarter.
The probability of selecting one coin is

Part A:
To find <span>the probability that all three coins are quarters if the first two envelopes Jeanne opens each contain a quarter, let the event that all three coins are quarters be A and the event that the first two envelopes Jeanne opens each contain a quarter be B.
P(A) means that the first envelope contains a quarter AND the second envelope contains a quarter AND the third envelope contains a quarter.
Thus

</span><span>P(B) means that the first envelope contains a quarter AND the
second envelope contains a quarter
</span><span>Thus

Therefore,

Part B:
</span>To find the probability that all three coins are different if the first envelope Jeanne opens contains a dime<span>, let the event that all three coins are different be C and the event that the first envelope Jeanne opens contains a dime be D.
