At Virginia Tech, a graduating CS student goes to career fair booths in the
technology sector (e.g., Google, Apple, Qualcomm, Texas Instruments, Motorola, etc)
and his/her likelihood of receiving an on-campus interview invitation after a career fair
booth visit depends on how well he/she did in his/her GPA. A student with a 3.9 GPA
results in a probability p = 0.95 of obtaining an invitation, whereas a student with a 3.0
GPA results in a probability of p 0.15 of an invitation.
(a)
the number of career fair booth visits a student must make to his/her first invitation
including the visit that results in the invitation. Express your answer in terms of
Give the probability distribution for the random variable Y that denotes
р.
On average, how many booth visits must student with a 3.9 GPA make
(b).
