Answer:

Step-by-step explanation:
In order to find the answer to this question you need to remember that if the denominator and the numerator are the same they equal one or one whole.




As long as the numerator and the denominator are the same they will be equivalent to 2/2 and 3/3.
Hope this helps.
Answer:
P(C|Y) = 0.5.
Step-by-step explanation:
We are given the following table below;
X Y Z Total
A 32 10 28 70
B 6 5 25 36
C 18 15 7 40
Total 56 30 60 146
Now, we have to find the probability of P(C/Y).
As we know that the conditional probability formula of P(A/B) is given by;
P(A/B) =
So, according to our question;
P(C/Y) =
Here, P(Y) =
and P(C
Y) =
{by seeing third row and second column}
Hence, P(C/Y) =
=
= <u>0.5.</u>

Answer:
43%
Step-by-step explanation:
If there are 43 yellow marbles out of 100 total, the fraction that will be used is 43/100. The percentage is found by dividing the numerator (top) by the denominator (bottom). The percentage is the first two numbers in the decimal. For future reference, if a decimal were to have more than 2 or 3 digits, the number would be rounded to the 4th and the decimal point would be placed between the 2nd and 3rd digits.
