a fair coin is flipped four times . use a tree diagram to find the probability of observing. exactly two heads . enter youe answer as a percentage to the nearesr percent
​

Answers

The probability of observing exactly two heads when a fair coin is flipped four times is found to the nearest percent to be 38%.

What is probability?

It is the ratio that shows the likelihood of an event occurring out of all the other possible events.

The tree diagram is drawn. The tree diagram is labeled such that the red lines represent the number of times exactly two heads are observed. The total number of events where exactly two heads are observed = 6The total number of events = 16

∴ P( Getting exactly two heads when a coin is flipped four times) = 6/16 = 0.375

Convert the into percent as follows:

0.375*100 = 37.5%

≈ 38%

Therefore, we have found the probability of observing exactly two heads when the coins are flipped four times to the nearest percent as 38%.

Answers

Answer:

x = 63.5°

Step-by-step explanation:

To find the value of x in the given right triangle, we would apply trigonometric function.

Reference angle = x

Side length Opposite to x = 17

Hypotenuse length = 19

Apply SOH:

[tex] sin(x) = \frac{Opp}{Hyp} [/tex]

[tex] sin(x) = \frac{17}{19} [/tex]

[tex] x = sin^{-1}(\frac{17}{19}) [/tex]

x = 63.474648° ≈ 63.5° (nearest tenth)

Let's solve your equation step-by-step.

10/a=15/24

Step 1: Cross-multiply.


10/a=15/24


(10)*(24)=15*a


240=15a


Step 2: Flip the equation.


15a=240


Step 3: Divide both sides by 15.

15a / 15 = 240/15

a=16
