1/2 (length times height)
Since Rosa ends up on the first floor, we'll set the equation equal to 1. We don't know Rosa's floor, so we'll set her floor as the unknown x. When she goes down, we'll subtract from her floor (x) and when she goes up, we'll add.
x= Rosa's floor
down 2= subtract 2
up 7= add 7
down 15= subtract 15
ends up on 1 so equation equals 1
x - 2 + 7 - 15= 1
combine like terms
x - 10= 1
add 10 to both sides
x= 11
ANSWER:
Rosa works on the 11th floor

Answer:
3.70% probability she allows more than one goal
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
X~Pois(0.3)
This means that 
In her next match, what is the probability she allows more than one goal?
Either she allows at most one goal, or she allows more than one goal. The sum of the probabilities of these events is decimal 1. So

We want
. So

In which






3.70% probability she allows more than one goal
