Given that events A and B are independent with P(A)=0.24P(A)=0.24 and P(B|A)=0.85P(B∣A)=0.85, determine the value of P(B)P(B), r

NemiM [27]

Answer:

P(B) = 0.85

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

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

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

$P(A) = 0.24, P(B|A) = 0.85$

These events are independent.

This means that $P(A \cap B) = P(A)*P(B)$ . So

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

$P(B|A) = \frac{P(A)*P(B)}{P(A)}$

$P(B|A) = P(B)$

$P(B) = 0.85$

Please, I need an answer to this question urgently.

Blababa [14]

Answer:

156

Step-by-step explanation:

While solving we will have to use the area formula of the rectangle, which is :A=w*l ; length*width=A.

Steps:
1)let’s consider that the shape is a full rectangle. => 16*12=192.

2)9*2=18 -> 18*2=36

3)192-36=156.

How do i solve this equation: 4/5a + 3 = 1/3a - 8

DENIUS [597]

You have to $subtract$ by $\frac{1}{3}a$ on $EACH$ of the $sides$ you're $working$ with!

$\frac{4}{5}a + 3 - \frac{1}{3}a - 8 - \frac{1}{3}a$

Which $gives$ us: $\frac{7}{15}a + 3 = -8$

$Now,$ that we got these $steps$ out of the way, let's $subtract$ $3$ from the sides you're working with!

$\frac{7}{15}a + 3 - 3 \\ = -8 -3$

$\frac{7}{15}(a) = -11$

We have gotten these $steps$ out of the way now lets $multiply$ by $\frac{15}{7}$ on your $sides$ because, it is the $reciprocal$ of $\frac{7}{15}$

So, $\frac{15}{7}( \frac{7}{15}a ) = \frac{15}{7} (-11)$

Cancel out: $\frac{15}{7}( \frac{7}{15} )$ because, it equals to: $1$

$\frac{15}{7}(-11) = \frac{-165}{7}$

Therefore, your $answer$ is: $\frac{-165}{7}$ $aka$ $23\frac{4}{7}$

Good luck on your assignment and enjoy your day
