Answer 1

To answer this question we will use the following expression to compute the probability that an event occurs:

`\frac{Favorable\text{ Outcomes}}{Total\text{ Outcomes}}.`

From the given table we get that

`800+425+700=1925`

sandwichs were without cheese or with sourdough from a total of

`800+425+700+1200=3125`

sandwichs.

Therefore:

`P(without\text{ chese or sourdough\rparen=}(1925)/(3125)=0.616.`

Answer:

`0.616.`
