Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly b successes on n repeated trials, and B can only have two outcomes.
In which is the number of different combinations of b objects from a set of n elements, given by the following formula.
And p is the probability of B happening.
In this problem we have that:
Bin(20,0.2).
This means that
(a) P(B=4).
(b) P(B≤1).
(c) P(B>1).
Either B is less than or equal to 1, or B is larger than 1. The sum of the probabilities of these events is decimal 1. So
We have that, from b),
So
Answer:
Step-by-step explanation:
(24 hours)/(5 knights) = 4.8 hours/knight
Look at .0=60*degrees
<span>Moved these terms to the left -60*degrees</span>
<span>It becomes </span>. 0- 60degrees= 0
Result<span>: -60 Degrees= 0</span>
because anything that you multiply or divide by zero would always equal zero. It's sort of just a rule of thumb
