Binomial probability: $P(k)=\left(\begin{array}{l}n \\ k\end{array}\right)\left(\frac{1}{5}\right)^{k}\left(\frac{4}{5}\right)^{n-k}$ A multiple choice test has five options per question. The probability of guessing correctly $k$ times out of $n$ questions is found using the formula shown. What is the probability a person scores a $70 \%$ by guessing randomly (7 out of 10 questions correct $) ?$

Question 73. Complete the pdf and answer the questions. In order to complete this, Pdf, we need to find the missing probability because all probabilities, some to one, we need to figure out that the probabilities that were given some to 90% in order to figure out our missing piece, we just simply subtract that 90% from one. We found that our missing piece is 0.1 to complete the third column. We just need to multiply the X values with their probabilities. Zero time, 0.30 one times 0.20 point two two times 0.1 Because you're a point, too. In three time 0.4, just 1.2. We have a question, eh? Find the probability that exit is too. Because we completed our pdf, you could just look in the table and find the probability of X B. And two is 0.1. Be buying the expected value they expected. Value is the summation. Every single ex multiplied with his probability. We've already done all of the X times the probabilities in the third column. So in this case, we're just simply adding together. The four numbers in the third column expected value is 1.6

In this problem, we have to use J B shares Terram to find deflection off all the numbers. Often did that Said that must like, begins the sixth standard deviations from the mean J B shares. Ted, I'm sex there. Brought any sight of numbers different. Shouldn't rely within k Standard deviations often need this. At least What blindness? What the right Bait by grace Quit. Oh, great. Great building one still right, baby Chef stood up the election off all the numbers over the press It that must live in six. Standard deviations probably mean this Agnese today cake? Well, 26 inch a vicious Tara, this is at least what minus one. Divided by six square, which is sick Will do one minus, but divided by 26. Which is it would do 26 minus but divided by 36 that this But maybe she s term. It is at least 35 divided by 36 bitches over required answer

In this problem. We have a used judicious terror to find deflection off parting numbers off a data set that must like Vidin t four standard deviations from the mean shabby ships dead on sticks bag. What? Any set of numbers? The fresh outbreak reliably be placed and that big nations off being me this at least right? Right, nurse right. The right made by base. Good. So I take you, shake it up. Reflection off, holding on both. We'll see Pete. Best say that must live with me. Four Standard deviations from the me This at least putting cake Where? 24 inch ambitious Terram. This is at least one minus one, divided by four square. So this is equal to buy minus by divided by 16. This is a quite do 16 minus well divided by 16. Oh, that is equal to 15 divided by 16. Or we can write the test at least 15 divided by 16 which is according to the JV shells. Terror At least 15 divided by 16 bitches over required answer

In this problem, we have to use judicious terror to find infection off oily numbers off a data set that must like bidden five standard deviations from the mean Jamie Shea Stadium States dead. But any said broke no bus. The direction that rely breeding place 100 big nations often mean respect least but minus right, Right, Right. The script that gets prettier then Bunce. So, Brett, big shift, Adam Reflection off or the numbers. Well, think me resting wreck must live within five Standard deviations from me. Front this right least, but think equal to fire. Injudicious terra we get it is at least one minus one, divided by five square. This is it Will do, but minus one divided by 25 that this 25 minus one divided by 25. So this is at least, but a vicious terram. This is at least 24 divided by 25 beaches over required answer
