Using the binomial distribution, it is found that there is a 0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.
For each household, there are only two possible outcomes. Either it has at least one VCR, or it does not. The probability of a household having at least one VCR is independent of any other household, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- 14 households, hence
. - 0.535 probability of having at least one VCR, hence
.
The probability of <u>at least 6 and no more than 8</u> is:

In which:




Then:

0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.

You have to do a system, lets say x are noble fir trees and y are douglas fir trees,
5x+3y=420
12x+9y=1080
if you solve this you get,
x=60 and
y=40
SO Noble fir trees cost $60 and Douglas fir trees cost $40.

Answer:
93
Step-by-step explanation:
by remainder theorem p(3) is the remainder
and therefore it is 93
Nico because 1 cm equals 10 mm, so Jake’s thumb is only 5.5 cm.
