By using the trial method we get a total number of trials taken by Charlie to see both sides of both the coins is 4.
<h3>What is probability?</h3>
Probability is the name of the area of mathematics that deals with the examination of random events. The ratio of favorable occurrences to the total number of events is used to calculate an event's probability.
P(E) = F(E)/T (E)P(E)
It stands for the probability that an event will occur.
F(E) = Amount of favorable occurrences
Total number of trials (T(E))
Given that Charlie has 2 fair coins.
If he tosses the pair of coins simultaneously, then the number of samples can be HH, HT, TH, TT.
So to see both sides of both the coins he should toss the coin four times.

Answer:
Step-by-step explanation:
1) 5
2) -3, which becomes 3
3) it would land at either 3, or -3
4) 7 or -7
5) if it is to the left, that means it is negative. there fore, your answer is -4
In this question , we have to find, which option represents inverse functions.
Let's check out option b
Let it be y
So we have
Switching x and y and solving for y,
Performing cross multiplication
Combining like terms
Which is same as of the other function.
So correct option is b .
Answer:
0.0183
Step-by-step explanation:
The percentage of students, who received their DTaP vaccine is 95%.
This implies that:
and
The standard deviation of the proportion is
We want to find the probability, that the sample proportion,
