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.
Answer:
0.75 gallon
Step-by-step explanation:
3 gallons of batter are poured equally into 4 bowls.
We have to calculate the amount of batter in each bowl.
so we have to divide 3 gallons by 4 to get the answer.
Total amount of batter = 3 gallons
divided into number of bowls = 4
The amount in each bowl = gallons
= 0.75 gallons
0.75 gallon of batter are in each bowl.
