Answer:
The correct answer would be, Yes the couple can be confident because the probability is close to 1.
Explanation:
According to the question, we are assuming that getting a boy or a girl is equally likely.
Hence;
P(getting a girl) = 1/
2
and
P(getting a boy) = 1/
2 in one birth.
Given the total number of children they plan to have = 6
P(there will be at least one girl) = 1 - P
(there will be no girl)
= 1 - P
(all of them are boys)
= 1 − (
1
/2
)
6
=
0.984375
Correct Answer: Yes because the probability is close to 1.
