Answer:
a
Step-by-step explanation:
hmmm let's find the distance between B and C first off.
hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
Answer:
P(x > 10) = 0.6981.
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this question:
P(x>10)
In which
So P(x > 10) = 0.6981.
Answer:
63
Step-by-step explanation:
Given:
a set of six elements
The solution would be like this for this specific problem:
number of subsets of n elements = 2^n
(2^6) - 1
= 64 – 1
= 63
