Answer:
The binomial distribution is called a probability distribution. This is a common discrete distribution that was used in the statistics.
Step-by-step explanation:
The binomial distribution is also named as a probability distribution. It is explained as the likelihood of the value will take the value of the two independent variables under the given parameters.
The binomial distribution is commonly called the discrete distribution. it is opposite to the normal distribution. The binomial distribution counts the two states which are represented as 1 and 0. It is usually used in social science statistics.
A. 84
B. 48
C. –84
D. –48
7 × (-3) ×(-2)2 =
7 × -3 × -4 = (you have to eliminate all parenthesis in the equation.)
7 × -12 = -84
so your answer would be: C
(a) Letters and digits that cannot be repeated will be 39,31,20,000.
(b) Letters and digits that can be repeated will be 6.76 × 10⁹.
(c) The letters are nonrepeated consonants and the digits that can be repeated will be 2.35 × 10⁹.
A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
The serial number on a bill consists of a letter followed by seven digits and then a letter.
A) Letters and digits cannot be repeated. Then the number of ways will be
⇒ 26 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 25
⇒ 39,31,20,000
B) Letters and digits can be repeated. Then the number of ways will be
⇒ 26 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 26
⇒ 6.76 × 10⁹
C) The letters are non-repeated consonants and the digits can be repeated.
⇒ (5 x 10⁷ x 5) + (21 x 10⁷ x 5) + (5 x 10⁷ x 21)
⇒ 0.25 × 10⁹ + 1.05 × 10⁹ + 1.05 × 10⁹
⇒ 2.35 × 10⁹

Answer:
408,844,800.
Step-by-step explanation:
(a) There are 26 letters in the alphabet and 10P7 ways of ordering 7 digits.
10P7 = 10!/3! = 604800
The answer is 26* 604800 * 26
= 26^2 * 604800
= 408844800.
