Answer:
Step-by-step explanation:
We are given the expression to be simplified:
Let us take common a term with a power of 5 from the numerator and the denominator of the given expression.
We know that:
Let us use it to solve the powers of 5 in the given expression.
we can write:
The given expression becomes:
Taking common from the numerator and
Taking common from the denominator
The answer is:
Answer:
a) 0.2316 = 23.16% probability that 0 carry intestinal parasites.
b) 0.4005 = 40.05% probability that at least two individuals carry intestinal parasites.
Step-by-step explanation:
For each trout, there are only two possible outcomes. Either they carry intestinal parasites, or they do not. Trouts are independent. This means that we use the binomial probability distribution to solve this question.
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.
You know that in a specific population of rainbow trout 15% of the individuals carry intestinal parasites.
This means that
Assume you obtain a random sample of 9 individuals from this population:
This means that
a. Calculate the probability that __ (last digit of your ID number) carry intestinal parasites.
Last digit is 0, so:
0.2316 = 23.16% probability that 0 carry intestinal parasites.
b. Calculate the probability that at least two individuals carry intestinal parasites.
This is
In which
So
0.4005 = 40.05% probability that at least two individuals carry intestinal parasites.
