Answer:
The probability that a birth was to a teen mother if we know that the pregnancy was unintended is 0.1942.
Step-by-step explanation:
Denote the events as follows:
<em>T</em> = birth was to a teen mother
<em>Y</em> = birth was to a young-adult mother
<em>A</em> = birth was to an adult mother
<em>U</em> = a birth was unintended
<em>I</em> = a birth was intended.
<u>Given:</u>
P (T) = 0.09
P (Y) = 0.24
P (A) = 0.67
P (I | T) = 0.23
P (U | T) = 0.77
P (I | Y) = 0.50
P (U | Y) = 1 - P (I | Y) = 0.50
P (I | A) = 0.75
P (U | A) = 1 - P (I | A) = 0.75 = 0.25
Consider the tree diagram below.
According to the Bayes' theorem,
Using the Bayes' theorem compute the probability that a birth was to a teen mother if we know that the pregnancy was unintended as follows:
The probability that a birth was to a teen mother if we know that the pregnancy was unintended is 0.1942.

(B ). A football team gained 3 yards on one play. The team lost 7 yards on the next play.
(C). A football team gained 3 yards on one play. The team gained 7 yards on the next play.
Answer:
(B ). A football team gained 3 yards on one play. The team lost 7 yards on the next play.

Which situation does it represent?
First, we simplify the expression as follows:
Remove brackets
Express each term with their signs
<u>Analysing each term;</u>
In terms of the list of given options,
+3 means a gain of 3 yards
-7 means a loss of 7 yards
<em>Hence, B. is correct</em>
