M and N are independent events. P(M | N) = 0.71. Find P(M)
mash [69]

Since M and N are independent events, P(M)=P(M|N)=0.71

Step-by-step explanation:

Two events A and B are said to be independent when the probability of A happening does not depend on whether B has happened or not.

In other word, this condition can be rewrite as follows:

P(A|B)=P(A)

where

P(A|B) is the probability of A happening  given that B has happened

P(A) is the probability of A happening

In this problem, we have:

- M and N are independent events: so M does not depend on whether N occurs or not

Therefore,

P(M)=P(M|N)

- Also, we know that

P(M|N)=0.71

Therefore, it follows that

P(M)=0.71

find the equation of the straight line passing through the point (0,1) which is perpendicular to the line y=-2x+2
Inessa [10]

Answer:

y = 1/2x + 1

Step-by-step explanation:

In order to evaluate a slope that is perpendicular to the given equation, you need to find the opposite reciprocal of the original slope. This means you take the original slope, flip the numerator and the denominator, and change the sign in front.

-2 ⇒ 1/2

Next, we need to substitute the information given into the point-slope formula.

The point-slope formula is:

y - y₁ = m(x - x₁)

y - 1 = 1/2(x - 0)

y - 1 = 1/2x

y = 1/2x + 1

Therefore, the line perpendicular to y = -2x + 2 is y = 1/2x + 1.
