Answer:

Step-by-step explanation:

3(2) + 4(-2) = -2 2(2)-4(-2) = -8

6 - 8 = -2 4 + 8 = -8

Correct Incorrect

3(6) + 4(-5) = -2 2(6) - 4(-5) = -8

18 - 20 = -2 12 + 20 = -8

Correct incorrect

3(4) + 4(4) = -2

12 + 8 = -2

incorrect

3(-2) + 4(1) =-2 2(-2) - 4(1) = -8

-6 + 4 = -2 -4 - 4 = -8

Correct Correct

Best way is process of elimination

A certain unsavory bar for poker-playing dogs is attended by only two types of dogs: "good dogs" and "bad dogs." For a randomly

SVETLANKA909090 [29]

Answer: The required probability is 0.1923.

Step-by-step explanation:

Since we have given that

Probability that it's a good dog = 0.4

Probability that it's a bad dog = 1-0.4 = 0.6

Probability that the dog smokes given that its a bad dog = 0.7

Probability that it smokes given that its a good dog = 0.25

According to question, probability of smoking pipe would be

P(good).P(Smoking pipe|good)+P(bad).P(smoking pipe|bad)

$0.4\times 0.25+0.6\times 0.7\\\\=0.1+0.42\\\\=0.52$

So, Probability of getting a good dog given that it is smoking pipe is given by

$\dfrac{P(good).P(smoking\ pipe|good)}{P(smoking\ pipe)}\\\\=\dfrac{0.4\times 0.25}{0.52}\\\\=\dfrac{0.1}{0.52}\\\\=0.1923$

Hence, the required probability is 0.1923.
