4. Suppose that 30 percent of the subscribers to a cable television service watch the shopping channel at least once a week. You are to design a simulation to estimate the probability that none of five randomly selected subscribers watches the shopping channel at least once a week. Which of the following assignments of the digits 0 through 9 would
Studdy Solution
STEP 1
1. The sample space is , representing "Yes", "No", and "Maybe".
2. The sum of probabilities for all outcomes in a sample space must equal 1.
3. Each probability must be between 0 and 1, inclusive.
STEP 2
1. Evaluate each set of probabilities to ensure they sum to 1.
2. Check that each probability is between 0 and 1.
STEP 3
Evaluate option a) :
Since the sum is not equal to 1, this is not a legitimate probability assignment.
STEP 4
Evaluate option b) :
The sum is equal to 1, so this is a legitimate probability assignment.
STEP 5
Evaluate option c) :
Since the sum is not equal to 1, this is not a legitimate probability assignment.
STEP 6
Evaluate option d) :
Since the sum is not equal to 1, this is not a legitimate probability assignment.
STEP 7
Evaluate option e) :
Since the sum is not equal to 1, this is not a legitimate probability assignment.
The legitimate probability assignment is option b) .
