Answer:
D. all of the above
Explanation:
The discrete probability functions consists of all the characteristics given in options.
For example,
(1) If we roll a dice 6 times, there are chances that Head will appear 2 or 3 times which is the well defined number of outcome.
(2) If we roll a dice 2 times, the probability of appearing Head could be 0,1 or 2 which satisfies the criteria that probability of any outcome must be greater than or equal to zero.
(3) Suppose if roll a dice once, there are 50% chances of appearing both Head and Tails and the sum of the probability is equal to 100% or 1.
Answer:
D. all of the above
Explanation:
All of the above mentioned conditions satisfies a discrete probability function.
For A:
i) If a die is rolled ones, there is probability of obtaining 1,2,3,4,5 or 6 as outcome which are well defined numbers
For B:
ii) If a coin is flipped ones, the probability of obtaining a head or a tail is 1 or 0. The probability of any outcome of any event is either greater than or equal to zero.
For C:
iii) The probability of an outcome for any event to occur is 1/2, the sum of outcome for all events occurs must be equal to one. (1/2)+(1/2)=1
