Find the missing probability.

1 answer:

4 0

The value of the missing probability is:

P(A) = 1/5

So the correct option is D.

<h3>How to find the missing probability?</h3>

First, we know that:

P(A∩B) = probability that events A and B are true = 3/100

And we also know that:

P(B|A) = probability that event B is true given that event A is true = 3/20

Here we have the rule:

P(A∩B) = P(B|A)*P(A)

Replacing the first two:

3/100 = (3/20)*P(A)

Solving for P(A), we get:

(3/100)*(20/3) = 1/5 = P(A).

So we conclude that the correct option for the missing probability is the one in option D.

Answer:

45 degrees

Step-by-step explanation:

Think of it like this the sum of the angles in a triangle are the always the same 180 degrees.

So now, we do 180 - 90 = 90 this is the sum of the other angles.

We shall assume that they are the same and divide 90/2 = 45 degrees each

Ok here are some things to understand while solving!

If three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.
If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
If two angles and the non-included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.
If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
Without knowing at least one side, we can't be sure if two triangles are congruent. (which we do!)

Hope this helped!
