Cabs depart from an airport according to a poisson process with rate λ per hour. each cab is loaded by a passenger with probability of p, independent of everything else. (a) determine the distribution of the time until the first passenger is loaded. (b) evaluate the probability that no passengers are loaded during a particular hour. (c) evaluate the expected number of cabs which are loaded by a passenger during a particular hour.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )

The correct answer is d, hope this
