which is a discrete random variable?\no y = \height of an emperor penguin on antarctica\\no z = \results of flipping two coins\\no w = \exact time it takes for a computer to update its software\\no x = \weight of the microprocessor inside your computer\
Answer
Answer:
C. Z = "results of flipping two coins"
Explanation:
Step1: Define discrete random variable
A discrete random variable has a countable number of possible values.
Step2: Analyze option X
Weight of a micro - processor is a continuous variable as it can take any value in an interval.
Step3: Analyze option W
Exact time for software update is a continuous variable as time is continuous.
Step4: Analyze option Y
Height of a penguin is a continuous variable as height can take any value in a range.
Step5: Analyze option Z
Results of flipping two coins can be {HH, HT, TH, TT}, which is a countable set of outcomes, so it is a discrete random variable.
