![### Probability of Selecting Girls from a Group of 14 Newborn Babies
Assume that a researcher randomly selects 14 newborn babies and counts the number of girls selected, \( x \). The probabilities corresponding to the 14 possible values of \( x \) are summarized in the given table. Answer the question using the table.
#### Probabilities of Girls
| x (girls) | P(x) | x (girls) | P(x) | x (girls) | P(x) |

#### Question:
**25) Find the probability of selecting 12 or more girls.**
Options:
A) 0.006
B) 0.007
C) 0.022
D) 0.001
To find the probability of selecting 12 or more girls, we sum the probabilities for \( x = 12 \), \( x = 13 \), and \( x = 14 \).
\[ P(x \geq 12) = P(12) + P(13) + P(14) \]
\[ P(x \geq 12) = 0.006 + 0.001 + 0.000 \]
So, \( P(x \geq 12) = 0.007 \).
