Answer:
a. 1/(2^n)
b. ¾
Step-by-step explanation:
a. Given that there are n variables in a compound proposition.
Each of the n variables have exactly two possible equally likely truth values that can be assigned.
The values are true or false.
And the value can only be either true or false at any given time
True(1) + False (1) = 2 truth values
So, the probability of each possible assignment of truth values to the n variables is 1/(2^n)
b. Given that a clause is in disjunctive form of exactly two distinct variables
n = 2 distinct variables; n = 2
1/(2^n) becomes
1/2²
= ¼
This means that there's exactly 1 combination out of possible 2² that will lead to the clause being false.
The probability that a given clause is true, given the random assignment of truth values from part (a) is calculated as 1 - ¼
= ¾
Answer:
-3
Step-by-step explanation:
To find the common ratio
Take the second term and divide by the first
6/-2 = -3
Check by taking the third term and dividing by the second
-18/6 = -3
And the fourth and dividing by the third
64/-18 = -3
The common ratio is -3
X was already negative so the only thing turning negative is Y!
So the first one is correct.
They all say the same thing
X ya era negativo, por lo que lo único que se vuelve negativo es Y!
Entonces el primero es correcto
X était déjà négatif donc la seule chose qui devient négative est Y!
Donc le premier est correct
X已经是负数,所以唯一变成负数的就是Y!
所以第一个是正确的
X已經是負數,所以唯一變成負數的就是Y!
所以第一個是正確的
