Orders for a computer are summarized by the optional features that are requested. the proportion of orders with no optional features is 0.38. the proportion of orders with one optional feature is 0.34. the proportion of orders with more than one optional feature is

0.28

Step-by-step explanation:

Let´s name the proportion of orders

The sum of all of these proportions is equal to the total quantity of orders.

Therefore,

N + O + M = 1

Then, substracting N and O on each side of that equation,

the proportion of orders with more than one optional feature (M) is:

M = 1 - N - O

M = 1 - 0.38 - 0,34

M = 0.28

the answer is 11.2 (i know i’m late)
