How many instants/sorceries do you need to turn Ghitu Lavaru

package ghitulavarunner;

        /*ASSUMPTIONS:
        - We consider a 60-deck with a 60-card deck with 24 lands, 4 Ghitu Lavarunner, and a certain number of spells.
    - We mulligan a hand if it contains 0, 1, 6, or 7 lands. In case of a mulligan, we ignore the free scry.
    - We assume that we are always able to cast any spell we draw. That is, the availability of colored mana to cast our spells is disregarded. This assumption is reasonable if the majority of our spells cost one or two mana. Suitably, those are exactly the type of spells that are ideal to support Ghitu Lavarunner.
    - We are on the play and on the draw with equal 50-50 probability.
    - We consider the following question: If I have a Ghitu Lavarunner in hand on turn 2 (or any other turn number to be manually adjusted in the SimulateGame function), then what is the probability of also having drawn two spells? In other words, we determine a conditional probability for settings where at least one of our cards (not necessarily the first one we draw) is already taken up by a Ghitu Lavarunner.
