balu736 [363]

Answer:

$Volume = 48in^3$

Step-by-step explanation:

Given

Required

The volume of the box

The number of boxes in each direction represents the length of that dimension.

So, from the attachment

$Width = 4in$

$Length = 3in$

The volume is:

$Volume = Length * Width * Height$

$Volume = 4in * 3in * 4in$

$Volume = 48in^3$

In the United States, 30% of people own a cat and 3% of people own a bird. What is the probability of someone owning both a cat

Alex777 [14]

Answer: 9/100

Step-by-step explanation:

Probability of people own a cat:

P(cat)=30/100=0.3

Probability of people own a bird:

P(bird)=3/100=0.03

Probability of both own a cat and a bird

P(cat and bird)=(30/100) × (3/100)

=90/1000=9/100=9%
