Tossing a dice and doing ultrasound

Gita was studying maths for her NAPLAN test. It was about basic probability concepts. 

“When you tossed a dice once, what is the chance it is 6” (the answer is 1 in 6). 

Her question was: “Why would people toss the dice only to know what number they will get?” and my answer was “It is to predict what will happen in the future. Sometimes we need to do it.”

So I gave her another simple example in basic probability. It was about guessing a baby’s sex from a pregnant mother. “What is the chance a mother will have a baby boy?”

And her answer was: “Why you should guess. You can go to the hospital and ask the doctor to do ultrasound.”

I am not happy.
