Answer:
2 x 2 = 4
Step-by-step explanation:
Two cookies plus another two cookies is 4. You can also use a multiplication table. :)
The probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.
<h3>What is the Venn diagram?</h3>
It is defined as the diagram that shows a logical relation between sets.
The Venn diagram consists of circles to show the logical relation.
We have:
f = 100 stamps in the collection
A = stamps in the 20th century
B = British stamps
We can make a linear equation to solve for x as the total stamps are 100 in the collection.

After solving x = 9.88, or x = -6.88
Probability can't be negative so neglecting the negative ones
x = 9.88
The probability that it is British:

= 61.64/100
= 0.6164
Thus, the probability that it is British is 0.6164 if the Venn diagram shows the information about a stamp collection. f = 100 stamps in the collection A = stamps in the 20th century B = British stamps A B. X(X - 6) х 2x + 32 28 A stamp is chosen at random.

Answer:
Train B is traveling faster.
Step-by-step explanation:
To find which train is faster, divide the distance the train traveled by the elapsed time for each train:
Train A:
Distance traveled is 12.5 meters.
Elapsed time is 1 second.
12.5 ÷ 1 = 12.5
Train A travels 12.5 meters per second.
Train B:
Distance traveled is 100 meters.
Elapsed time is 4 seconds.
100 ÷ 4 = 25
Train B travels 25 meters per second.
25 is greater than 12.5, so train B travels faster.

P(X=1) = 1/36
P(X=2) = 3/36 = 1/12
P(X=3) = 5/36
P(X=4) = 7/36
P(X=5) = 9/36 = ¼
P(X=6) = 11/36

7/36
Step-by-step explanation:
1-
Attached, you will find a table with the possible values of X.
(See table attached)
As we can see, there are 36 entries so,
<em>P(X=1) = 1/36
</em>
<em>
</em>
<em>P(X=2) = 3/36 = 1/12
</em>
<em>
</em>
<em>P(X=3) = 5/36
</em>
<em>
</em>
<em>P(X=4) = 7/36
</em>
<em>
</em>
<em>P(X=5) = 9/36 = ¼
</em>
<em>
</em>
<em>P(X=6) = 11/36
</em>

It can be noticed that the only possible value of X which is divisible by 4 is 4 and there are 7 entries in the table, so
P(X divisible by 4) = P(X=4) = 7/36
