Toss all 4 coins together 50 times and keep a tally sheet while doing so. How many tally's for each genotype did you get?

Here is my answer. When I toss 4 coins together 50 times and kept a tally sheet while doing so, here are the number of tally's I got for each genotype:

BB=12.5

Bb=25

Bb=12.5

In this case, this gives me the probability of the following:

BB=25%

Bb=50%

bb=25%

Hope this answers your question.
