It can be too late to save for retirement. You want to begin saving at least 45 years before you plan to retire.
<h3>When to start savings for retirement?</h3>
Retirement is when labour stops working at a regular job. When a person retires, they would have a reduced source of income. This is why it is important to save for retirement. The earlier one starts to save for retirement, the more money the person would have when they retire.

Answer:
If its numbers are higher
Answer:
a)
And replacing we got:
b) D. No, because the probability of this occurring is not small.
Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Part a
If 15 people are randomly selected, find the probability that at least 13 of them have brown eyes.
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:
And replacing we got:
Part b
Is it unusual to randomly select 15 people and find that at least 13 of them have brown eyes? Note that a small probability is one that is less than 0.05.
Since our calculated probability is too higher compared to 0.05 we can conclude this:
D. No, because the probability of this occurring is not small.
Answer
A little over 16.
Step-by-step explanation:
If you convert 5 liters to milli-liters, you get 5,000. You then divide 5,000 by 300 and get 16.67.
