Answer:
There is a 25.52% probability of observating 4 our fewer succesful recommendations.
Step-by-step explanation:
For each recommendation, there are only two possible outcomes. Either it was a success, or it was a failure. So we use the binomial probability distribution to solve this problem.
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 problem we have that:

If the claim is correct and the performance of recommendations is independent, what is the probability that you would have observed 4 or fewer successful:
This is

In which







There is a 25.52% probability of observating 4 our fewer succesful recommendations.
Answer:


Step-by-step explanation:
Because there are two smaller lines drawn in lines TA and AK, it means that the length of TA is the same as AK.
Hence, 
Subtract 4x from both sides:


Divide both sides by 2:


To find TK,

If you divide X which is 5 by 5, then you will get 1.
5^1 will be 5.
5 divided by 0 does not have a solution. It is not a number.
It is possible to subtract an integer with a negative sign from another number, for example 5-(-3). Multiplying two negative signs will make the sign positive, so the problem would then be this: 5+3. That equals 8.
1+1-1x1/1= 1
