( I) -y13 ygtOfey) = 3 ~

elsewhere

(a) If two such fuses have independent lengths of life YI and Y2 find the joint probability

density function for Y1 and Y2 (5)

(b) One fuse in (a) is in a primary system and the other is in a backup system that comes into

use only if the primary system fails The total effective length of life of the two fuses is then Yj

+ Y2 Find P(Yj + Y2 1) (5)

1 The probability of a customer arrival at a grocery service counter in any 1 second is equal to

015 Assume that customers arrive in a random stream and hence that the arrival any 1 second

is independent of any other

(a) Find the probability that the first arrival will occur during the third I-second interval (5)

(b) Find the probability that the first arrival will not occur until at least the third I-second

interval (5)

2 Let the moment-generating function for Y be met) et +~e2t +le 31 bull Find the distribution

of Yand its expected value and variance (10)

3 As a measure of intelligence mice are timed when going through a maze to reach a reward of

food The tirne(in seconds) required for any mouse is a random variable Y with density

function given by

bl ygt b f(y)= ly2 shy

o elsewhere

where b is the minimum possible time needed to traverse the maze

(a) Show that frY has the properties of a density function (5)

(b) Find F(y) (3)

(c) Find P(Ygt b + c) for a positive constant c (2)

4 A soft drink machine can be regulated so that it discharges an average of f1 ounces per cup If

the ounces of fill are normally distributed with standard deviation of 03 ounce give the setting

for f1 so that 8-ounce cups will overflow 1 of the time (10)

5 The length of life(measured in hundreds of hours) Y for fuses of a certain type is modeled by

the exponential distribution with

density function for Y1 and Y2 (5)

(b) One fuse in (a) is in a primary system and the other is in a backup system that comes into

use only if the primary system fails The total effective length of life of the two fuses is then Yj

1 The probability of a customer arrival at a grocery service counter in any 1 second is equal to

015 Assume that customers arrive in a random stream and hence that the arrival any 1 second

is independent of any other

(a) Find the probability that the first arrival will occur during the third I-second interval (5)

(b) Find the probability that the first arrival will not occur until at least the third I-second

interval (5)

2 Let the moment-generating function for Y be met) et +~e2t +le 31 bull Find the distribution

6 6 6

of Yand its expected value and variance (10)

3 As a measure of intelligence mice are timed when going through a maze to reach a reward of

food The tirne(in seconds) required for any mouse is a random variable Y with density

function given by

bl ygt b f(y)= ly2 shy

o elsewhere

where b is the minimum possible time needed to traverse the maze

(a) Show that frY has the properties of a density function (5)

(b) Find F(y) (3)

(c) Find P(Ygt b + c) for a positive constant c (2)

4 A soft drink machine can be regulated so that it discharges an average of f1 ounces per cup If

the ounces of fill are normally distributed with standard deviation of 03 ounce give the setting

for f1 so that 8-ounce cups will overflow 1 of the time (10)

5 The length of life(measured in hundreds of hours) Y for fuses of a certain type is modeled by

the exponential distribution with

( I) -y13 ygtOfey) = 3 ~

elsewhere

(a) If two such fuses have independent lengths of life YI and Y2 find the joint probability

density function for Y1 and Y2 (5)

(b) One fuse in (a) is in a primary system and the other is in a backup system that comes into

use only if the primary system fails The total effective length of life of the two fuses is then Yj
