Here are the records of two different sequences (A,B ) of a coin tossed eight times. A: T H H H H H H H B: H T T H T H H T If yo
ser-zykov [4K]

Answer: Sequence B is more probable than A.

Step-by-step explanation:

This two sequences are not equally probable. Sequence B is more probable than A due to the equal chances of getting head (H) and a tail (T). The probability of getting a head is equal to the probability of getting a tail which is 4/8 i.e 0.5

The sequence A is less probable because the head(H) occur more than tail (T). The probability of head occurring is almost a sure event i.e 1 which is not feasible.

Un padre cede al mayor de sus hijos la quinta parte de su capital, al segundo la cuarta parte del mismo y al tercero le da el re
spayn [35]

Answer:

El padre tenía un capital de 60,000 euros.

El hijo mayor recibe 12,000 euros.

El hijo segundo recibe 15,000 euros.

El hijo tercero recibe 33,000 euros.

Step-by-step explanation:

Sea x el capital total del padre y a,b,c son las asignaciones a los hijos mayor, segundo y tercero. A continuación, construimos las ecuaciones matemáticas a partir de lo descrito en el enunciado:

Hijo mayor

a = \frac{1}{5}\cdot x (1)

Hijo segundo

b = \frac{1}{4}\cdot x (2)

Hijo tercero

c = \left(1-\frac{1}{5}-\frac{1}{4}\right)\cdot x = 33000 (3)

De (3) tenemos que el capital del padre es:

x = \frac{33000}{1-\frac{1}{5}-\frac{1}{4}  }

x = 60000

El padre tenía un capital de 60,000 euros.

Por (1) y (2) determinamos los capitales del hijo mayor y el hijo segundo:

a = \frac{1}{5}\cdot x

x = 12000

El hijo mayor recibe 12,000 euros.

b = \frac{1}{4}\cdot x

b = 15000

El hijo segundo recibe 15,000 euros.
