A country's flag has three horizontal stripes: one red, one blue, and one green, so there are six possible ways the colors can be arranged on the flag with three horizontal stripes: Red-Blue-Green, Red-Green-Blue, Blue-Red-Green, Blue-Green-Red, Green-Red-Blue, Green-Blue-Red.
The three colors (red, blue, and green) can be arranged in horizontal stripes on a flag. Since there are three colors and each color can be placed in one of the three stripes, we can find the number of arrangements by using the fundamental counting principle, which states that the total number of possible outcomes is equal to the product of the number of choices for each stage of the process.
Hence, a country's flag has three horizontal stripes: one red, one blue, and one green, so there are six possible ways the colors can be arranged on the flag with three horizontal stripes: Red-Blue-Green, Red-Green-Blue, Blue-Red-Green, Blue-Green-Red, Green-Red-Blue, Green-Blue-Red.

played
in many countries around the world. The marimba is a percussion instrument, a type of xylophone nearly ten feet long. The forerunner of the modern marimba comes from Guatemala. The instrument, however, is even older in its origins, which are thought to be Mayan.
The marimba consists of a set of wooden keys or bars that are hit with two or more mallets to make musical sounds. Some pieces of music require the use of up to six mallets. The instrument slightly resembles a piano, but the musician plays the marimba standing up instead of sitting down.
The marimba is not
special
because of its wooden bars. Instead, resonators, the metal tubes that hang beneath each bar, are what make the marimba unique. They are made in different lengths and produce different sounds and tones. Some resonators are made of aluminum, but brass is preferred. Resonators were originally made of hollowed-out gourds. The mallets also make a great difference in the quality of the sound. Softer mallets are used for the low
notes
. Harder mallets are used for the high notes.
It takes a great
deal
of skill to handle multiple mallets, two or three in each hand. Some musicians have developed special grips to help them control the mallets as they play. One of these, the Stevens method, uses four mallets, two in each hand. The grip involves holding one of the mallets with the ring and pinky fingers while the other is controlled between the thumb and the middle finger.
