Pennant squares are used in genetics and involve probabilities that are integer multipliers of one half to integer powers

Such as 0, 1/4, 2/4, 3/4

There was an examp!e problem that involved a 1 / 3 and a 2 / 3

This should not happen

I asked the biology tracher and she said there is a condition that causes death before being born 1 in 4 times

( 1 / 4 ) / ( 3 / 4 ) = 1 / 3
( 2 / 4 ) / ( 3 / 4 ) = 2 / 3

The 1 / 4 death was not registered in the records

Not her exact words
