Statistical Independence / Probability Problem Please show your work so I can try to understand :)...
You are approaching a traffic signal. If the probability of encountering a red light is 0.50 and the probability of seeing a green light is 0.40, what is the probability of encountering a yellow light? 0.90 0.10 0.001 0.20 If 60% of students have an iPhone, 30% have an iMac computer, and 20% have both an iPhone and an iMac, how may students could be identified as an Apple customer having either an iPhone or iMac? 0.90 1.10 0.20 0.70...

3. Use the following table to answer the questions. -100 -80 -40 0 10 P(XSx)0.35 0.43 0.64 0.871 a) Find the probability that X is at most -50. b) Find the probability that X is more than -10. c) Find the probability that X is between (inclusive) -90 and 0. d) Construct the corresponding pdf. e) Calculate the variance of x.
if all steps can be listed please. I'm super confused.
thanks!
Find the probability. 7) Refer to the table below for events in a sample space, S, compute P(CIE). A D 0.12 E 0.03 Totals 0.15 B 0.50 0.10 0.60 C 0.08 0.17 0.25 Total 0.70 0.30 1.00
Please anyone can help me with this probability question and please provide explanation. Thank you so much! (i) Consider two events A and B, with P(A) = 0.3, P(B) = 1. Compute P(A∩B), P(Ac ∩B), and P(A ∩ Bc) (where we denote by Ac = Ω \ A the complement of an event A). (ii) We now consider three independent events A, B, and C. Using the definition of inde- pendence, show that the two events Ac and Bc ∪...
Probability theory question, please help solve in full so I can
understand as well. Thank you!! (will give positive rating)
A box contains 15 resistors, 6 diodes, and 9 capacitors. 1. 2 parts are taken from the box. Consider the following events: A) the first part is resistor B) the first part is diode C) the first part is capacitor Find the following probabilities a) p(A)-? g) p(E/A)=? h) p(E/B)=? D) the second part is resistor E) the second part...
PLEASE explain why and show work so I can try to follow and
understand!! Thank you!!
Q1)
Consider two events P and Q.
a. Write the general formula used to calculate the probability
that either event P occurs or Q occurs or both occur.
b. How does this formula change if:
i. Events P and Q are disjoint (i.e., mutually exclusive of each
other).
ii. Events P and Q are nondisjoint events that are statistically
independent of each other.
iii. Events P and Q are nondisjoint events that are
statistically dependent of each other.
Q2)
Rewrite...
Please show all work, step by step, so I can understand what to do. Ten trials are conducted in a Bernoulli process in which the probability of success in a given trial is 0.3. If x = the number of successes, determine the following: a. E(x) b. σx c. P(x = 5) d. P(4 ≤ x ≤ 8) e. P(x > 4)
This is a probability theory question, please help solve with
full workings so I can understand as well as I need it to revise.
*I will give postive rating* Thank you!!
There are 20 students in the group. 9 students have excellent preparation for the exam, 6 have good level of knowledge, 3 have average level of knowledge, and 2 are bad prepared. Probability that student pass the exam for excellently prepared student is 100%, if student have good level...
PLEASE SHOW ALL WORK ON PAPER (so I can understand steps)
Problem 3: You have 50,000 dollars that you plan to invest in a portfolio with two stocks, A and B. The price of stock A is currently $20. You expect that the stock price will be: A) $60 if the economy is booming (which could happen with probability 25%), B) $25 if the economy continues at its current state (which could happen with probability 40%) C) $5 if the...
