- How do we determine the probabilities of having multiple independent events resulting in two or more 'successes'? For example, when rolling 5 six-sided dice, what are the odds that 2 or more result in a 5 or 6? What about the odds that exactly 3 roll 4?Please do not give solution in image formate thanku.Suppose we know that the probabilities P(A) = .5, P(B|A) = .3 and P(A or B) =.3. What is the value for P(A and B)? What is the value for P(B)?
- Suppose A and B are two events with probabilities: P(A) = .45, P(B) = .55, P(A N B) = .15. a) What is (A|B) ? b) What is (B|A) ?A person rides uber 30% of the time, her roommate gives her a ride 30% of the time and she rides with her mom 40% of the time. She is late 10% of the time with her roommate she is late 3% of the time when she rides uber and 7% of the time when she rides with her mom. What is the probability that she wil be on time if she rides with her roommate?Air-USA has a policy of booking as many as 22 persons on an airplane that can seat only 20. (Past studies have revealed that only 83% of the booked passengers actually arrive for the flight.) Find the probability that if Air-USA books 22 persons, not enough seats will be available. prob = %3D Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less? Ono, it is not low enough to not be a concern Oyes, it is low enough not to be a concern What about defining unusual as 10% or less? Oyes, it is low enough not to be a concern O no, it is not low enough to not be a concern Question Help: Message instructor D Post to forum Calculator Submit Question
- The probabilities are 0.4, 0.2 and 0.3 and 0.1, respectively, that a student uses LAN,Wifi, Prepaid Data, or Hotspot for internet connection. What is the probability thatamong 10 randomly selected students, 2 use LAN, 4 use Wifi, 3 use prepaid data,and 1 uses Hotspot for their internet connection?If two events are complimentary what is the probability of P(A and B) ?3. What is the law of large numbers? If you were using the relative frequency of an event 500 to estimate the probability of the event, would it be better to use 100 trials of trials? Explain. but probabilities
