3x^2-7x+4=0 solve for x. Write both solutions separated by a comma

$Hi \\ \\ 3x\²-7x+4 ~~--\ \textgreater \ \boxed{\frac{-b\pm \sqrt{b\²-2ac} }{2a} } \\ a=3 \\ b=-7 \\ c=4 \\ \\ x= \frac{7\pm \sqrt{(-7)\²-2.3.4 } }{2.(3)} \\ \\ x= \frac{7\pm5}{6} \begin{cases}x_1= \frac{7+5}{6}=2 \\ \\ x_2= \frac{7-5}{6}= \frac{1}{3} \end{cases} \\ \\ \therefore~(2; \frac{1}{3}) \\ \\ \\$

A bucket always contains two balls. Ball colors are red and blue. Each stage in a process consists of two steps: selection and r

KonstantinChe [14]

Answer:

Probability that the fifth ball selected is red = 0.705

Step-by-step explanation:

Let

$X_{n}$ = Number of red balls after the 4th turn

⇒ $X_{n}$ ∈ { 0, 1, 2 }

Then,

P = $\left[\begin{array}{ccc}0.8&0.2&0\\0.1&0.8&0.1\\0&0.2&0.8\end{array}\right]$

⇒ $P^{4} = \left[\begin{array}{ccc}0.487&0.435&0.776\\0.218&0.565&0.218\\0.776&0.435&0.487\end{array}\right]$

Now,

P(5th ball is red | $X_{0}$ = 2 ) = 0. $P^{4} _{20}$ + $\frac{1}{2}P^{4} _{21} + 1. P^{4} _{22}$

= $\frac{1}{2} (0.4352) + 1. (0.4872) = 0.2176 + 0.4872$

= 0.705

∴ we get

Probability that the fifth ball selected is red = 0.705
