Answer:
4.39% theoretical probability of this happening
Step-by-step explanation:
For each coin, there are only two possible outcomes. Either it lands on heads, or it lands on tails. The probability of a coin landing on heads is independent of other coins. So 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.
Theoretically, a fair coin
Equally as likely to land on heads or tails, so
10 coins:
This means that
What is the theoretical probability of this happening?
This is P(X = 2).

<h2>Answer:The graph of 
is the graph of 
compressed vertically.</h2>
Step-by-step explanation:
Given that and
is always positive because
is always positive.
is always positive because
is always positive.
So,both are always positive.
So,there is no flipping over x-axis.
In ,the height of a point at
is
In ,the height of a point at
is
So,height of any point has less height in than
So,the graph of is the graph of
compressed vertically.
