Identify different character components for a given typeface: Arial.
Shkiper50 [21]

Answer: Arial belongs to the sans serif family of typefaces. It is the most commonly used typeface, and it is the default typeface set in Microsoft Word. A character is a typographic element represented through an upper- or lowercase letter, number, or special character. Every letter of the alphabet has multiple parts that we describe with a particular set of terms. Typographers call this “letter anatomy.” The basic terms common to all letters are below:

An ascender is the stroke extending upward, going above the x-height (which is the height of the letter excluding the ascender or descender).

A descender is the stroke extending downward from the baseline (which is the imaginary horizontal line that aligns the bodies of the characters).

A bar is the horizontal stroke in the uppercase letters A, E, F, H, I, and T, as well as in the lowercase letters e, f, and t.

A counter is the blank space within the body stroke.

A bowl is a curved stroke that surrounds the counter.

A shoulder is a curved stroke beginning at the stem.

A serif is the tapered feature at the end of a stroke. Arial is a sans serif font, and it does not have tapered corners at the ends of the main strokes.

A bowl contains 20 candies; 15 are chocolate and 5 are vanilla. You select 5 at random. What is the probability that all 5 are c
Sindrei [870]

Answer: 0.1937

Explanation:

Given : A bowl contains 20 candies; 15 are chocolate and 5 are vanilla.

If we select 5 candies, then the number of ways to select them is given by permutations.

The number of ways to select 5 candies is given by :-

^{15}P_5=\dfrac{15!}{(15-5)!}=\dfrac{15\times14\times13\times12\times11\times10!}{10!}=360360

The number of ways of selecting any 5 candies out of 20:-

^{20}P_5=\dfrac{20!}{(20-5)!}\\\\=\dfrac{20\times19\times18\times17\times16\times15!}{15!}\\\\=1860480

Now, the probability that all 5 are chocolate :-

=\dfrac{360360}{1860480}=0.193691950464\approx0.1937

Hence, the probability that all 5 are chocolate =0.1937
