Of customers ordering a certain type of computer, 15% order an upgraded graphics card, 30% order extra memory, 20% order both the upgraded graphics card and extra memory, and 35% order neither. Fifteen orders are selected at random. Let 1,2,3,4 denote the respective number of orders in the four given categories. A. Find P(1=3,2=4,3=2,4=6).

2.0104*10^(-9)

Step-by-step explanation:

Given that of customers ordering a certain type of computer, 15% order an upgraded graphics card, 30% order extra memory, 20% order both the upgraded graphics card and extra memory, and 35% order neither

15 orders are selected at random

P(x1=3, x2 =4, x3 =2 and x4 =6) where x1 , x2, x3 and x4 represent the upgraded graphics, extra memory, both and neither respectively.

Each order is independent of the other.

P(x1) = 0.15, P(X2) = 0.30 , P(x3) = 0.20 and P(x4) = 0.35

Since independent we  get

P(x1=3) =

P(X2=4) =

P(X3=2) =

P(X4=6) =

Required probability = Product of all these four

= 2.0104*10^(-9)

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
