To calculate this probability is often easier to calculate the complement
the prob that we are looking for is 1-P(No salt packed in dinner)
Note: No salt packed with dinner is the complement event of having salt packed within
so let's find this probability
He is what we know
if John packs 4/45 chance no salt included
if Sue packs 3/70 chance no salt
if Marry packs 2/25 No salt
We are looking into probability is the sum (note these events are disjoint)
final result should be 1- that sum
The answer is A. 28.5 hope this helped!!!! :)
Answer:
F=50
Step-by-step explanation:
F=5*10=50
Use the equation
A= 2(wl +hl +hw)
Where
w is width
h is height
l is length
