Step-by-step explanation:
"COUNTY FAIR" involves 10 letters
<h3>Part A</h3>
<u>The probability of winning is 10 out of 26:</u>
<h3>Part B</h3>
<u>Expected number of winners with 52 contestants:</u>
The experiment result is almost twice less (12 vs 20).
In order to change the results of experimental probability some of the letters may need swapped, (probably the letters are in alphabet order) but for this we need more data.
Answer:
1. A resposta é a opção C.
2. ( a +b )² = a² + 2ab + b² Verdade
( a - b )² = a² - 2ab + b² Verdade
( a + b ) .( a – b) = a² + b² Falso
( a +b)³ = a³ + 3a²b + 3ab² + b³ Verdade
( a -b)³ = a³ - 3a²b + 3ab² - b³ Verdade
3. a.) m² - 14am + 49a² = ( m - 7a)²
b) m2 – 9n² = m² - (3n)² = (m + 3n)(m - 3n)
c) 30+ 5xy + 12a +2axy = (6 + xy)(5 + 2a)
d) 8a²b + 10ab² = 2ab( 4a + 5b)
