How are conditional probability and independent events related?

artcher [175]

Answer:

1. P(A|B) - option 2

2. does not affect - option 2

3. P(A) - option 1

Step-by-step explanation:

By the definition, the notation P(A|B) reads the probability of event A given that event B has occured. So, for the first gap correct choice is 2 - P(A|B).

If events A and B are independent, then the probability of event B occuring does not affect the probability of event A occuring. So, for the second gap correct choice is 2 - does not affect.

Events A and B are independent, then

$P(A\cap B)=P(A)\cdot P(B)$

Use formula for the conditional probability:

$P(A|B)=\dfrac{P(A\cap B)}{P(B)}$

Since events A and B are independent, we get

$P(A|B)=\dfrac{P(A)\cdot P(B)}{P(B)}=P(A)$

So, for the third gap correct answer is 1 - P(A)

Explain how to solve 2^x + 1 = 9 using the change of base formula log base b of y equals log y over log b. Include the solution

elena55 [62]

Answer:

$x=2.170$

Step-by-step explanation:

The given equation is $2^{x+1}=9$ .

We take logarithm of both sides to base 2 to get:

$\log_2(2^{x+1})=\log_29$

Apply the power rule of logarithms to get:

$x+1=\log_29$

We now apply the change of base formula:

$x+1=\frac{\log_{10}9}{\log_{10}2}$

$x+1=\frac{0.9542}{0.3010}$

$x+1=3.1701$

$x=3.1701-1$

$x=2.1701$

To the nearest thousandth, $x=2.170$

Meg and Tanner take a road trip together where they take turns driving. The ratio of the number of miles that Meg drives to the

frez [133]

Answer:

Step-by-step explanation:

$\frac{Meg}{Tanner}$ = $\frac{4}{3}$

total dist. driven = dist. Meg drove + dist. Tanner drove

Meg = 112

Tanner = x or how far did Tanner drive?

$\frac{112}{x}$ = $\frac{4}{3}$

$\frac{3}{4}$ * 112 = x

84 =x so Tanner drove 84 miles

total driven = 112 + 84

total driven = 196 :)
