3 13
of the animals in a pet shop are rabbits and
6
13
are hamsters.
What is the probability that an animal chosen at random from the pet shop
is a rabbit or a hamster?
Give your answer as a fraction in its simplest form.

The person will most likely choose a hamster. As you can see 3/13 and 6/13 are equivalent fractions. 6/13 is greater than 3/13 and 6/13 represents the hamsters. There are more hamsters than rabbits so the rabbit will most likely be picked. The probability is 1/2.

Step-by-step explanation:

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
