Answer:
Step-by-step explanation:
P(X > 6) = ?
P(X > 6) = P(X = 6) + P(X = 7) + P(X = 8)
P(X > 6) = 0.118 + 0.035 + 0.004
P(X > 6) = 0.157
Thus the probability of getting 6 or more girls in 8 births is 0.157
The probability of getting a girl is 12 . The probability of getting 6 girls is therefore (12)6 . Since we have 6 girls, we also need to find the probability of getting 2 boys, which is (12)2 . There are (86)=28 ways to get 6 girls out of 8 children.
