Answer:

P(A given B) = 3/4

Step-by-step explanation:

As we know that it is conditional probability, where the probability of an event depends on the event that has certain probability of occurrence.

The formula for conditional probability is:

P(A given B) = P(A ∩B) / P(B)

Where a and B are events. The probability of event B is known and we also know probability of A∩B

So, putting the values in the formula:

P(A\ given\ B) = \frac{P(A and B)}{P(B)}\\= \frac{\frac{3}{10} }{\frac{2}{5} } \\=\frac{3}{10} *\frac{5}{2}\\=\frac{3}{4}

So, the probability of A given B is 3/4 ..

Answer:

x = 14

y = -3

Step-by-step explanation:

Given

2x + 8y =4

x = -3y + 5

Required

Solve

Substitute x = -3y + 5 in 2x + 8y =4

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

Open bracket

-6y + 10 + 8y =4

Collect like terms

-6y +  8y =4-10

2y =-6

Divide both sides by 2

y = -3

Substitute y = -3 in x = -3y + 5

x = -3 * -3 + 5

x = 9+ 5

x = 14

The example on direct variation is illustrated below based on the information given.

<h3>How to illustrate the direct variation?</h3>

An example will be:

When x = 2, y = 10. Find the value of y when x is 6.

In this case, this will be calculated thus:

y = kx

10 = 2k

k = 10/2

k = 5

Since y = kx.

y = 5 × 6

y = 30

The value of y is 30.
