Answer:
0.0319
Step-by-step explanation:
To approximate this probability, we shall be using the Bernoulli approximation of the Binomial distribution.
Let p = probability of selecting a reference book = 65% = 0.65
Let q = probability of selecting other books= 1-p = 1-0.65 = 0.35
Now, we want to find the probability that all of these 8 books to be re-shelved are reference book.
We set up the probability as follows;
P(X = 8) = 8C8 •p^8•q^0
P(X = 8) = 1 * (0.65)^8 * (0.35)^0
P(X = 8) = 0.031864481289 which is 0.0319 to 4 decimal places
Answer:
360
Step-by-step explanation:
using the definition
n 
= 
where n! = n(n - 1)(n - 2)..... × 3 × 2 × 1
then
6
= 
= 
= 
← cancel 2(1) on numerator / denominator
= 6 × 5 × 4 × 3
= 360
