File Edt View History Bookmarks People Window Help ponses/submit?dep-16598928 The results of a recent television survey of American TV households revealed that 80 out of every 100 TV households have at least one remote control. What is the probablity that a randomly selected TV household does not have at least one remote control? (Enter your answer as a fraction.) 1s the statement cerrect? The probability that a certain stock will increase in value over a period of 1 week is 0.8. Therefore, the probability that the stock will decrease in value is 0.2. O Correct, because the sum of the probabilities equals 1 Incor ect, because the sum of the probabilities does not equal 1, O Incorrect, because the value of the stock could stay the same. Incorrect, because the time period ds to b-shorter than a week. 0 Incorrect, because the time period needs to be longer than a week.

Explanation / Answer

question 1

Since the probabilities are mutually exclusive, either the event will happen (A) or it will not happen ("not A"):

1 = P(A) + P(A not)
1 = (80/100) + P(A not)
20/100 = P(A not)

The probability that a randomly selected TV household does not have at least one remote control is 20/100 = 1/5= 0.20

question 2

incorrect,stock value could stay same or decrease.

question 3

we know that

p(E U F)=P(E)+P(F)-P(E and F)

=0.6+0.4-0.2

=0.8
