Evaluation of an exact expression to obtain the percentage of all random nucleotide sequences of a given length (n) that can be sequenced with semiconductor sequencing given a certain number of flows (k).

1 | ```
flowsRandom(k = 300, n = 150)
``` |

`k` |
Integer. Number of flows available during semiconductor sequencing. |

`n` |
Integer. Length of the random sequences to be sequenced. |

`P` |
Percentage of sequences that are completely covered |

`Q` |
Percentage of sequences that are not completely covered |

`delta` |
1 - (P + Q), should be a small number when calculation is accurate |

`N` |
Number of summands for calculation of P |

`M` |
Number of summands for calculation of Q |

`summands` |
N + M = total number of summands |

### To compute the percentage of covered sequences of length 150 with 300 flows run:
flowsRandom(300,150)
