Answer:
x=25
Step-by-step explanation:
First, we add all like terms. Then, we solve for x.

We can rearrange some things because order does not matter with addition. Next, we just use basic equation solving techniques.

Answer: 25/676
Step-by-step explanation:
Number of possible outcomes = 26
In other to win, one must draw must be either (A, E, I, O or U) 
Therefore required drws to win = 5
First draw:
P(win) = Total required outcome / Total possible outcome 
P(win) = 5/26
Second draw:
P(win) = Total required outcome / Total possible outcome 
P(win) = 5/26
Therefore, 
P(winning twice) = (5/26) × (5/26) = 25/676
