Question

XX=Female XY=Male.

Answer 1

Answer:

50% or 1/2

Explanation:

The probability of their 6th child being a girl would be 50% or 1/2.

During meiosis, the female produces X eggs while the male produces X and Y sperms. A random fusion of gametes then occurs during fertilization.

                             XX    x    XY

       XX (female)   XY (male)   XX (female)   XY (male)

XX - 1/2 or 50%

XY - 1/2 or 50%

Hence, the probability of producing a girl is 1/2 or 50% irrespective of the number of kids a couple might have produced already.
