Answer: Option D
means that of the 4 people who have a brother, 2 of them also have a sister
Step-by-step explanation:
Events are defined as follows.
Event A: The selected person has a sister
Event B: The selected person has a brother
The conditional probability of A given B is the probability that the selected person also has a sister since he has a brother.
This is:
We know that
P(B) is the probability that the selected person has a brother. Notice that there are 4 people who have a brother.
P(A and B) is the probability that the selected person has a brother and also a sister. Notice that there are 2 people who have a brother and a sister.
So means that of the 4 people who have a brother, 2 of them also have a sister
Answer:
see below (I hope this helps!)
Step-by-step explanation:
Let's take the number 10 for example. Its prime factorization is 2 * 5. Removing the 2 leaves us with just 5, and since 5 has 2 factors, we know that 10 has 2 even divisors. I think that the reason why it's not working for you is that you are using odd numbers, keep in mind that if a number has an even divisor, it is automatically even so in this case, we're talking about even numbers only.
A few more examples:
Number = 30, prime factorization = 2 * 3 * 5, removing a 2 leaves us with 3 * 5 = 15, 15 has 4 factors so we know that 30 has 4 even divisors.
Number = 26, prime factorization = 2 * 13, removing a 2 leaves us with 13 and 13 has 2 factors so we know that 26 has 2 even divisors.
