(a)
Answer to Problem 5OE
The twoevents are independent.
Explanation of Solution
Given information:
The given information is
Calculation:
Independent Event: - When the outcome of one event doesn’t affect the outcome of others.
Dependent Event: - When the outcomes of one event affect the outcome of others.
Probability that both erasers are green
Theoutcome of one event doesn’t affect the outcome of others, so the twoevents independent.
Thus,the twoevents are independent.
(b)
To find:The event in each problem is the dependent or independentevents.
(b)
Answer to Problem 5OE
The
Explanation of Solution
Given information:
The given information is
Two light bulb of
Two light bulb of
Calculation:
Independent Event: - When the outcome of one event doesn’t affect the outcome of others.
Dependent Event: - When the outcomes of one event affect the outcome of others.
The Probability of choosing one
Then after this there are three light bulbs remaining,
The probability of choosing a
Thus the probability of choosing a watts then a watt bulb is denoted by
The two events are dependent as the outcomes of one event affect the outcome of others.
Thus,the two events are dependent.
