Meaning of Risk and Uncertainty Risk: In Common Parlance‚ risk means a low probability of an expected outcome. From business decision-making point of view‚ risk refers to a situation in which a business decision is expected to yield more than one outcome and the probability of each outcome is known to the decision makers or can be reliably estimated. For example‚ if a company doubles its advertisement expenditure‚ there are three probable outcomes: i) Its sales may more than double ii)

answer is C. Q4) Which of the following relations is correct for the three measures of central tendency? A. Median = Mode + 2 Mean B. 3 Median = Mode − 2 Mean C. Mode = 3 Median − 2 Mean D. 3 Mode = Median + 2 Mean Answer The relation between the three measures of central tendency is given by‚ 3 Median = Mode + 2 Mean ⇒ Mode = 3 Median − 2 Mean The correct answer is C.
