Part (a)
There are 7 red out of 7+3 = 10 total
<h3>Answer: 7/10</h3>
==========================================================
Part (b)
We have 3 green out of 10 total
<h3>Answer: 3/10</h3>
==========================================================
Part (c)
3/10 is the probability of getting green on any selection. This is because we put the first selection back (or it is replaced with an identical copy)
So (3/10)*(3/10) = 9/100 is the probability of getting two green in a row.
<h3>Answer: 9/100</h3>
==========================================================
Part (d)
Similar to part (c) we have 7/10 as the probability of getting red on each independent selection.
(7/10)*(7/10) = 49/100
<h3>Answer: 49/100</h3>
==========================================================
Part (e)
7/10 is the probability of getting red and 3/10 is the probability of getting green. Each selection is independent of any others.
(7/10)*(3/10) = 21/100
<h3>Answer: 21/100</h3>
==========================================================
Part (f)
We have the exact same set up as part (e). Notice how (7/10)*(3/10) is the same as (3/10)*(7/10).
<h3>Answer: 21/100</h3>

Answer:
Janet reads 13.865 pages in 4.7 minutes.
Step-by-step explanation:
Given that Janet can read 2.95 pages of a book in a minute.
- unit rate = 2.95 pages/per minute
As she reads for 4.7 minutes.
We just need to multiply 4.7 minutes with 2.95 to determine total pages she would read in 4.7 minutes.
i.e.
4.7 × 2.95 = 13.865 pages
Therefore, Janet reads 13.865 pages in 4.7 minutes.
Answer:
24
Step-by-step explanation:
Just subtract the first quartile form the third quartile.
third quartile - first quartile
32 - 8 = 24 IQR
FIRST quartile: 8
SECOND quartile: 20
THIRD quartile: 32
So the IQR is 24
Hope this helps :)
