If you flip two coins 96 times what is the best prediction for the number of times they would both land on tails

Flipping two coins gives four possibilities: HH, HT, TH, TT

So P(TT)=1/4

So we'd expect a quarter of the trials to be two tails.

[tex]\frac 1 4 \times 96 = 24[/tex] trials expected to be two tails.
