(a)
The probability for getting atleast one 2.
(a)
Answer to Problem 17IP
The probability of getting atleast one 2 is
Explanation of Solution
Given information:
The spinners are at the right is spun once. The tree diagram is used to determine the probabilities as,
Formula Used:
Calculation:
A tree diagram would give the following possible outcomes:
In order to keep the probabilities the same,
So, there are 16 possible outcomes.
There are 7 outcomes where there is at least one 2. So, P (at least one 2) is
Conclusion:
The probability of getting atleast one 2 is
(b)
The probability for getting atleast one 3.
(b)
Answer to Problem 17IP
The probability for getting atleast one 3 is
Explanation of Solution
Given information:
The spinners are at the right is spun once. The tree diagram is used to determine the probabilities as,
Formula Used:
Calculation:
A tree diagram would give the following possible outcomes:
In order to keep the probabilities the same,
So, there are 16 possible outcomes.
There are 4 outcomes where there is at least one 3.
So, P (at least one 3) is
Conclusion:
The probability for getting atleast one 3 is
