Brian flips a fair coin 3 times. What is the probability of getting 3 heads?

earnstyle [38]

If Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

The given statement is Brian flips a fair coin 3 times.

We need to find the probability of getting 3 heads.

<h3>What is probability?</h3>

Probability refers to possibility. A random event's occurrence is the subject of this field of mathematics. The range of the value is 0 to 1.

The possible outcomes are {HHH, THH, HTH, HHT, TTH, THT, HTT, TTT}.

Total number of outcomes = 8

The number of favourable outcomes =1

So, the probability of getting 3 heads = 1/8 = 0.125

Hence, if Brain flips a coin 3 times the probability of getting 3 heads is 0.125.

A 100-gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. The function

kykrilka [37]

Answer:

- Stretching the parent function $f(x) =\frac{1}{x}$ vertically .

- Shifting the parent function $f(x) =\frac{1}{x}$ 5 units right.

Step-by-step explanation:

<h3>The complete exercise is: " A 100 gallon fish tank fills at a rate of x gallons per minute. The tank has already been filling for 5 minutes. The function $f(x) = \frac{100}{x -5}$ represents the remaining time in minutes needed to fill the tank. How is the graph of the parent function $f(x) =\frac{1}{x}$ transformed to create the graph of $f(x) = \frac{100}{x -5}$ ?"</h3><h3 />

Below are some transformations for a function :

1. If $f(x)+k$ , the function is shifted "k" units up.
