The quantity of coins that Josh spots when strolling to work is a Poisson irregular variable with

mean 6. Each coin is similarly prone to be a penny, a nickel, a dime, or a quarter. Josh overlooks the

pennies yet gets different coins.

(a) Find the normal measure of cash that Josh gets on his approach to work.

(b) Find the fluctuation ot the measure of cash that Josh gets on his approach to work.

(c) Find the likelihood that Josh gets precisely a quarter on his approach to work.

Consider an arrangement ot free preliminaries, each ot which is similarly prone to bring about any of the

results O, 1, .

m. Say that a round starts witn the primary preliminary, and that another round starts

each time result O happens. Allow N to indicate the quantity of preliminaries that it takes until the entirety of the

results O, 1, .

m 1 nave happened in something very similar round. Likewise, let T. indicate the quantity of

preliminaries that it takes until j unmistakable results have happened, and let mean thefih particular result
