Answers
Step-by-step explanation:
Atlantis, a likely mythical island nation mentioned in Plato’s dialogues “Timaeus” and “Critias,” has been an object of fascination among western philosophers and historians for nearly 2,400 years. Plato (c.424–328 B.C.) describes it as a powerful and advanced kingdom that sank, in a night and a day, into the ocean around 9,600 B.C. The ancient Greeks were divided as to whether Plato’s story was to be taken as history or mere metaphor. Since the 19th century there has been renewed interest in linking Plato’s Atlantis to historical locations, most commonly the Greek island of Santorini, which was destroyed by a volcanic eruption around 1,600 B.C.
The given question is If a shopkeeper earns Rs.400 a day when it is a weekend and Rs.300 a day when it is a working day. What should be his earning expectation if the probability of it being a weekend today is 0.6?
In the given question we have to find what should be the earning expectations of the shopkeeper
The options given are A) 240 B) 120 C) 360 D) 700.
From the data, the probability of today being a weekend is 0.6
The weekend day earning of a shopkeeper is Rs.400
The required earning expectation of a shopkeeper
for the weekend with the given probability is calculated as
E = W * P.
where E is the earning expectation.
W is the earning on a weekend day.
P is the probability.
Substituting the values in the given formula, we get the answer as
E = W * P
E = 400*0.6
E = 240.
Therefore 240 should be his earning expectation the probability of it being a weekend today ks 0.6
Hence, option A)240 is said to be the correct option for this problem.
