Five standard six-sided dice are rolled. We are told there is no three-of-a-kind, but there is a pair of dice that show the same
Neko [114]

The probability that after re-rolling these three dice, at least three of the five dice show the same value is  \frac{4}{9}

Of the three dice rolled, one may match the original pair and two are different, and this can occur three ways:

(\frac16 \times \frac56 \times \frac56 ) + ( \frac56 \times \frac16 \times \frac56 ) + ( \frac56 \times \frac 56 \times \frac 16 )  =  \frac {75}{216}

[ where \frac{1}{6} is the probability of matching the first two and \frac{5}{6} is the probability of not matching the first two ]

Or, two may match the original pair and one is different

( \frac16 \times \frac16 \times \frac 56 ) + ( \frac16 \times \frac56 \times \frac 16 ) + ( \frac56 \times \frac16 \times \frac16 )  = \frac {15}{216}

Or, all three may match the original pair

( \frac 16 \times \frac 16 \times \frac 16 )  = \frac {1}{216}

Or, all three may  be the same, but not match the original pair:

( \frac 56 \times \frac 16 \times\frac 16 )  =  \frac {5}{216}

[ where \frac{5}{6} is the probability of getting a new number and \frac{1}{6} is the probability of matching that new number ]

Adding these together: \frac {75}{216} + \frac {15}{216} + \frac 1{216} + \frac 5{216}  =  \frac {96}{216}  = \frac 49

A truck driver can travel 560 miles on 28 gallons of gas. How far can he travel on 35 gallons of gas?
Shtirlitz [24]
560 / 28 = 20....so the driver travels 20 miles per gallon

on 35 gallons......35 * 20 = 700 miles <==

or u can also do it this way...

560/28 = x / 35....560 miles to 28 gal = x miles to 35 gal
cross multiply because this is a proportion
(28)(x) = (560)(35)
28x = 19600
x = 19600/28
x = 700 miles <==

so u can either do it by finding the unit rate or by making a proportion. either way will result in the same answer.
