Answer:
0.2706 ; 0.05265 ; 0.1353
Explanation:
Given that :
λ = 2
According to the poisson distribution formula :
P(x = x) = (λ^x * e^-λ) / x!
P(x = 1) = (2^1 *e^-2) / 1!
P(x = 1) = (2 * 0.1353352) = 0.2706
P(x ≥ 5) = 1 - P(x < 5)
1 - P(x < 5) = 1 - [p(x = 0) + p(x = 1) + p(x = 2) + p(x = 3) + p(x = 4)]
We obtain and add the individual probabilities. To save computation time, we can use a poisson distribution calculator :
1 - P(x < 5) = 1 - (0.13534+0.27067+0.27067+0.18045+0.09022)
1 - P(x < 5) = 1 - 0.94735 = 0.05265
P(x ≥ 5) = 1 - P(x < 5) = 0.05265
Probability that no emails was received :
x = 0
P(x = 0) = (2^0 *e^-2) / 0!
P(x = 0) = (1 * 0.1353352) / 1 = 0.1353
Answer: $27000
Explanation:
The amount of goodwill impairment on December 31, 2020 will be:
Amount if goodwill = Net book value - Fair value
= $792,000 - $765,000.
= $27000
Therefore, the amount of Goodwill is $27000
3.20 is the real risk-free rate
<h3>What is
risk-free rate?</h3>
The risk-free rate of return, commonly abbreviated as the risk-free rate, is the rate of return on a hypothetical investment with scheduled payments over a set period of time that is assumed to meet all payment obligations.
Subtract the inflation rate from the yield on the Treasury bond that corresponds to the duration of your investment to calculate the real risk-free rate.
The risk-free rate determines the return an investor can expect from an investment over a specified time period. A risk-free rate is calculated by deducting the current inflation rate from the total yield of the treasury bond that corresponds to the investment duration.

Answer:
Placebo effect
Explanation:
Placebo effect occurs when an individual starts to show positive response to an inactive substance after being told the substance has powers to cure.
