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.
WHAT IS THE PROBLEM WITH SOCIAL SECURITY? The answer is a long-term shortfall. Social Security plans for solvency over 75 years, but because of demographic pressures and the weak economy, it is currently solvent only until 2033.

DNA. The normal DNA will become inactive and thus permitting the host DNA to
continue it normal process.</span>
