# Question: Refer to the Journal of Engineering Computing and Architecture Vol

Refer to the Journal of Engineering, Computing and Architecture (Vol. 3., 2009) study of cell phone handoff behavior, Exercise 3.58 (p. 134). Recall that a “handoff” describes the process of a cell phone moving from one base channel (identified by a color code) to another. During a particular driving trip a cell phone changed channels (color codes) 85 times. Color code “b” was accessed 40 times on the trip. You randomly select 7 of the 85 handoffs. How likely is it that the cell phone accesses color code “b” only twice for these 7 handoffs?
