The right answer for the question that is being asked and shown above is that: "e. It is not possible to determine if the events are independent." You have two events A and B such that P(A|B) = 0.4 and P(A) = 0.4. Based on this information, you can conclude that e. It is not possible to determine if the events are independent.<span>

To find the value of x, you need to set up a proportion.This is the proportion you would set up:
2.5 x
---- = ------
3.75 60
x=40
Answer:
20%
Step-by-step explanation:
To find the decimal answer, we just do 5/25 which is equivalent to 0.2
Then, we multiply 0.2 by 100 to get the percentage:
0.2*100=20
Answer:
Step-by-step explanation:
Multiply across.
Then Simplify.
For all probability exercises, the probability is always
(the number of possible 'successful' results)
divided by
(the total possible number of results).
1). Number of diamonds in the deck = 13
Total cards in the deck = 52.
Probability = (13/52) = 1/4 = 25%
2). Probability of the first one being a diamond = 1/4 .
Now there are 51 cards left, and 12 of them are diamonds.
Probability of the second one being a diamond = 12/51
Probability of both events =
(1/4) x (12/51) = 3/51 = about 5.88% (rounded)
3). First one is a diamond: 13/52
Now there are 51 cards left, and 13 of them are clubs.
Second one is a club: 13/51.
Probability of both events = (13/52) x (13/51)
= 169/2652 = about 6.37% (rounded)
4). Same logic, same solution, as #3.
5). 6.37% chance that it happens with the diamond coming up first,
6.37% chance that it happens with the club coming up first.
Probability of either one happening = 12.74% (rounded).
