Flow of trafic at a certain trafic corner is modeled as a sequence of bernoulli trials by assuming that the probability of a car passing during any given second is a constant p. assume that the bernoulli trials at each second is independent of any other trials. suppose a pedestrian can cross the street only if no car is to pass during next 3 seconds. let x a random variable denoting the waiting time of the pedestrian at that corner (a) find p(x 1). (b) find p(x = 4).

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

what are you trying find out?

step-by-step explanation:

2 over 5 and 4 over 15

don’t know last one sorry

step-by-step explanation:

school a:

minimum value is 2

maximum value is 22

the lower quartile is 2.5

the median is 10

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12

the median is 16

the upper quartile is 18

box plot for school a isn't symmetrical. the data tails on the right

box plot for school b isn't symmetrical. the data tails on the left

hope i
