Second Option:
"green marble out of the same jar, without replacing the first marble"
Step-by-step explanation:
Two events r and s are independent if the probability that r occurs does not affect the probability that s occurs.
When choosing an object of some color b from a jar with n objects where there are x objects of the desired color b, the probability of obtaining 1 object of color b when randomly selecting an object from the jar is:
If after taking the object it does <em>not return</em> it to the jar (without replacement) then, now the probability of obtaining an object of color b is:
if the one selected in the first trial was the color b.
if the one selected in the first test was not the color b
Note that now the probability P <em>depends on the result obtained in the previous test.</em>
<em>This event is </em><em>dependent</em><em>.</em>
However, if by take object b in the first test, and the object is <em>returned</em> to the jar, and then the second test is made, then
.
The probability does <em>not depend on the result of the first trial</em>. The same happens if the objects are taken from <em>different jars</em>.
<em>These would be </em><em>independent</em><em> events.</em>
Finally the correct option is the second option.
Answer:
1 2 3 4 5 6
2 ÷ 15 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 5
Step-by-step explanation:
As it is mentioned in the question that the probability of faces like 2,3,4,5 are not affected so in this case
P(2) = P(3) = P(4) = P(5) = 1 ÷ 6
And, P(6) = 0.2
As we know that
P(1) + P(2) +P(3) +P(4) +P(5) +P(6) = 1
This results P(1) = 2 ÷ 15
So,
1 2 3 4 5 6
2 ÷ 15 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 6 1 ÷ 5
Hence, the correct option is 2nd
The first thing we must do for this case is find the factors of each of the numbers.
We have then:
60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
Therefore the GCF is given by:
So, by rewriting the sum we have:
The error is not having written the GCF multiplying.
Answer:
Xiao did not write the sum as the product of GCF and the sum of two numbers.
The correct expression is:
