Answer:
If there are 1000 customers in the store one week, how many will purchase exactly one of these items
1000 CUSTOMERS*28%=280
Step-by-step explanation:
A The event that a persons buys a suit
B The event that a person buys a shirt
C The event that a person buys a tie
P(A)= 22%
P(B)= 30%
P(C)= 28%
P(AB)=
11%
P(AC)=
14%
P(BC)=
10%
P(ABC)=
6%
A u B u C Is the event that any item is bougth
AC u AC u BC Is the event that any two events occured
So the wanted probability is
P[(A u B u C )(AB u AC u BC)^c
P[(A u B u C )=P(AB)+ P(BC)+P(BC)
P[(A u B u C ) =0.22+0.30+0.28-0.11-0.14.-0.10+0.06
=0,51
0,51=+0,23+P[(A u B u C )(AB u AC u BC)^c
=0,28
1000 CUSTOMERS*28%=280

(Notice that we always have
and
, then solve for
:




(this is the inverse)
###
This inverse is valid only for
. Why?
Suppose we take
. Then

This would suggest that in the original equation, we should get
when
. But when we check this, we end up with

which is clearly not true.

Answer:
<u>1.5 or 1 1/2 kilograms were rotten and thrown out</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of kilograms of tomatoes Sheldon picked = 5 3/10
Amount of kilograms of tomatoes rotten = 1.5
2. How many kilograms of tomatoes were rotten?
<u>1.5 or 1 1/2 kilograms were rotten and thrown out</u>
