Answer:0.0228
Explanation:
Assuming the letter of Alphabet A is a random variable which represents the small bowl and the letter of Alphabet B is the random variable which represents the large bowl.......
Therefore, the total amount of large bowl and small bowl is B+A and the difference between the large bowl and the small bowl is B-A....................
The first thing to do is to find the variance followed by the determination of the z-score.
(A). Variance= σ= √( σ^2(B) + σ^2(A)..........-----------------------------------------------------------------------------------(1)..
Then,
σ= √(0.4^2 + 0.3^2).
σ= 0.5.
(B). Hence, we calculate for the z-factor.
Therefore, z= 0 - 1/ 0.5.
= -2.
So, P(B - A < 0) = 0.0228.
Answer:
The correct answer to the following question will be "Decisions under risk".
Explanation:
- When those risks are known or could be inferred, the option of an appropriate strategy based on such probabilities is called under-risk decision-making.
- Risk means a degree or a level of uncertainty as well as an inability to effectively predict the effects or effects of an event.
Therefore, it's the right answer.
I think the question here asks for Canada and US: those two countries are know to be popular immigrant choices.
Also, while Greenland is part of Northern America, it has been closer associated with Europe, and it's rarely actually called a "northern American country"
