Two vertices of a right triangle have coordinates (5, 1) and (2, -1). The line segment created by connecting these points is the hypotenuse of the right triangle. Which could be the coordinate of the third vertex?

(2, 1)

(1, -1)

(2, -5)

(2, 5)

probability that a girl will be born next is 5/9

Step-by-step explanation:

Total outcome = 40 + 50 = 90

Probability of an event = Number of favorable outcomes

                                          Total number of outcomes

therefore, probability that the baby born next will be a girl =  50 / 90 = 5/9
