abruzzese [7]

Answer:

C. He found the midpoint of a segment.

Step-by-step explanation:

The midpoint is the point that divides a segment into two equal parts. Thus it is located at the middle of the segment.

John used this simple method to determine the midpoint of a segment. For example, let a segment AB = 10 cm be folded in half. A point made at the fold would be at 5 cm, which is the midpoint of the segment.

Thus the appropriate answer to the question is option C.

A group of 10 students participate in chess club, karate club, or neither.

Ira Lisetskai [31]

Answer: Option B

$P(A|B)=0.50$

Step-by-step explanation:

We look for the conditional probability of A given B.

This is written as:

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

First we must find the probability of A and B

There are 10 students in total. Note that of those 10 students only 2 of them are at the same time in the karate club and in the chess club

Therefore:

$P(A\ and\ B)=\frac{2}{10}$

There are 10 students in total. Note that of those 10 students only 4 of them are in the chess club

Then:

$P(B)=\frac{4}{10}$

Finally:

$P(A|B) = \frac{P(0.2)}{0.4}=0.50$
