Math Problem Statement
a. Find the probability of getting exactly 6 girls in 8 births.
Solution
To find the probability of getting exactly 6 girls in 8 births, we need to look at the corresponding value of when in the provided table.
From the table:
- When (the number of girls), .
Thus, the probability of getting exactly 6 girls in 8 births is .
Would you like a detailed explanation of how this table might have been constructed, or have any other questions?
Here are 5 follow-up questions for further exploration:
- What is the probability of getting at most 4 girls in 8 births?
- What is the probability of getting at least 5 girls in 8 births?
- How would you calculate the expected number of girls in 8 births using this table?
- What is the probability of getting exactly 4 or exactly 6 girls in 8 births?
- How would you compute the variance for the number of girls in this distribution?
Tip: The sum of all probabilities for to must equal 1 in a valid probability distribution. Always check this when dealing with such tables.
