Beginner at using Mathematica, and having trouble with nested lists. For example, the following output for 15 coinflips every day for a year:

```
cointoss1 = Table[cointoss2 = RandomChoice[{"H", "T"}, 15], 365]
```

Which gives an output like:

```
{{"H", "T", "H", "T", "T", "T", "T", "T", "H", "T", "T", "H", "H",
"T", "T"}, {"H", "H", "H", "T", "H", "T", "H", "H", "H", "T", "T",
"H", "T", "H", "T"}...
```

My question is how would I be able to count the number of times I get a certain element in the list. For example, If I wanted to count how many heads I get within each list how would I go about doing it. I’ve tried using count –

```
Count[cointoss1, "H"]
```

Every time I tried it I have gotten an output of 0. I want to get it in a list like output for the number of heads in each list:

{5,8,…}

Another thing I want to find is the number of lists with x or more heads. So how would I go about doing this? Apologies for the bad formatting, this is my first question.
