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.
<span>The answer is d) All of the above. Like playing the 'telephone game', when one person passes information on to another the information can be distorted by things like their ability to remember it clearly and their own feelings about the content. They may also add or take away from the content based on their own life experiences and feelings.</span>
