The Z&C virus has caused a slowdown in the economy over the world. Both the property and stock markets have tumbled quite a bit. Alex is a real estate investor and believes that now is the best time to buy properties for investment. He has recently bought 10 units in the newly developed FloraLife Community, with a unit price of $1.8M. He plans to sell the 10 units five years later and expects that each selling price follows an independent normal distribution with a mean of $2.2M and a standard deviation of $0.6M. Alex needs to pay 2% of the selling price to his agent for selling the units. What is the probability that Alex will not make profits from any unit among the 10 units?

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
