Assume 3 breads are all different, 3 meats are all different and 2 cheeses are all different. A sandwich contains a type of bread, a type of meat and a type of cheese. The number of different types of sandwiches that can be made is
The correct choice is (C).
Answer:
2.25
Step-by-step explanation:
substitute x = -2 into y = (2/3)^x
=> y = (2/3)^-2
=> y = 9/4 = 2.25

Answer:Pois(ln(200))
Step-byy-step explanation:
Let N be the number of received calls in a day
That is
N∼Pois(λ).
0.5% = 0.5/100 = 1/200 of no calls
P(N=0)=e^−λ=1/200
-λ=e^(1/200)
λ=in(200)
Our number of calls in a day is distributed Pois(ln(200)).
X= 9 x=2
-2 × -9=18
-2 + -9= -11
