each member had. The gender of the parent was also considered. The

results are summarized here:

1).Males with one child made up 0.15 of the membership.

2). Females with 2 children also made up 0.15 of the membership.

3). For those with 3 or more children, the probability that the

parent was female was 0.5 (I.e., of the members who had

3 or more children, half of those members were female.)

4).Males with no children made up 0.05 of the membership.

5). Males with 3 or more children made up 0.1 of the membership.

6). For those members who were male, the probability that they

had no children was 0.125

7). when all members were considered, the probability of having

no children was 0.15

Question:

a)What is the probability of parent being male, given that

the member (parent) had 2 or more children?

b) What is the probability of parent being female, given that

the member (parent) had fewer than 2 children?

I draw a table like this:

0 1 2 3

male 0,05 0.15 - 0.1

female 0.1 - 0.15 -

0.15

But for finding answers for questions I need to find all elements in my table....I used all given features except 3) and 6). After finding all elements in table which are "-" I will just use conditional probability formula. But before help me please to find elements in the table...;( thank u....
