1. Consider the experiment of tossing a fair coin four times. The coin has two possible
outcomes, heads or tails.
a. List the sample space for the outcomes that could happen when tossing the
coin four times. For example, if all four coin tosses produced h
To resolve this I will start by finding out how many standard deviations is the value from the
mean using the formula
Z=
X
and the result of this is approximately 0.67 standard
deviations from the mean. After that we can say that P(male > 70) = P(Z > 0.6
The binomial distribution is a discrete probability distribution because it describes the
probability of occurrence of each value of a discrete random variable, which is a variable that
has distinct values.

A normal distribution is a probability distribution when this normal distribution is defined by a
function or table that links each outcome of an experiment with its probability of occurrence.
In a normal distribution, the percentage of the area under a
Probability is the measure of how likely something is to happen.
A sample space is a collection of all possible results for an experiment or activity.
Event-based refers to the measurement of the results of an event or multiple events.

As defined in the website mathinsight.org, a random variable is a variable that is subject to random
variations so that it can take on multiple different values, each with an associated probability. Random
variables can be discrete or continuous. An examp
For the assignments this week, I asked 10 of my friends, 5 males and 5 females, how much did they pay
for their last haircut? The results for the males were $20, $25, $28, $30, and $17. For the females, the
results were $46, $53, $50, $24, and $60. For de
