Answer:
A: They are independent because P(X). P(Y) = PIX and Y).
Step-by-step explanation:
A) Two events X and Y are said to be independent if the probability of X occurring does not affect the probability of Y occurring or the probability of Y occurring does not affect the probability of X occurring. An example of independent events is the rolling of a die and flipping of a coin because the probability of getting a face in the die does not influence the probability of getting a head or tail in the coin. The probability of both events occurring is given as:
P(X and Y) = P(X).P(Y)
To write 311/500 as a decimal you have to divide the numerator by the denominator of the fraction. We divide now 311 by 500 what we write down as 311/500 and we get 0.622.
311/500 as a decimal equals 0.622.
X - y
4 - 5 = -1
The difference between x and y is -1.
8 - 1 = 7
The answer for when y = 8, x = 7.
