Determine the missing probability value for the probability distribution. $$\begin{array}{|l|c|c|c|c|c|} \hline \boldsymbol{x} & 0 & 1 & 2 & 3 & 4 \\ \hline \boldsymbol{P}(\boldsymbol{x}) & 0.07 & 0.20 & 0.38 & ? & 0.13 \\ \hline \end{array}$$

No. At 44 uh, by one.

They want us and they give us our table. That nine turns 14 hundreds of that. Well, her 2100 that 15 Acors 38 hundreds of the time, um occurs 19 hundreds of the time. And last, there's another value. 21 occurs seven hundreds of the time and we end up with the expected value as for point before.

Mhm. According to the definition, the probability that the random variable X. Is greater than we called you, too, because The probability that equals two plus the probability the articles. Mhm. Which vehicles .05 plus .05 Read trickles .1. Mhm. Mhm. And the expectation he calls the south of exciting times its probability. And so there's Eco's zero times 0.8, last one times, mhm 0.1 plus two times .05 Plus three times .05. And this tickles .35 Yeah, participation.

Mhm. The probability That the random variable is greater than or equal to two Equals the probability that it equals to plus the probability that it equals three plus the probability that it equals four And this equals .05, 1.05 Plus zero Robot, Their vehicles .1 thought, and the expectation echoes the sun of the value of X I times its probability metric, als zero times 00.7 Plus one times .15 plus two points times 0.5 plus three times 30.5 and plus four times 40.5 Hence their sickles, points 15 last 0.1 Plus .15 plus point to Which vehicles .6.
