Description Usage Arguments Value Author(s)

This function can be used to analytically determine the expected
probability that an MC item is solved correctly, as opposed to the
simulation approach used in `workMCItem`

.

1 | ```
mc_analytical(accuracy, n_options = 4, sd_sol = 1)
``` |

`accuracy` |
Accuracy value of an assumed test taker |

`n_options` |
number of answer options in the MC item |

`sd_sol` |
Standard deviation of the solution distribution. Distractor SD is always 1 |

The expected probability that the item is solved correctly
