1/10 because there are ten outcomes

Answer:  The correct option is (B) 0.10.

Step-by-step explanation:  Given that ten outcomes are all equally likely from an event and we choose one of them at random.

We are to find the probability that the outcome we chose will be the outcome of the event.

Since the outcomes are equally likely, so

let A denotes the event that any one of the outcome is chosen and S be the sample space for the experiment.

Then, n(A) = 1 and n(S) = 10.

Therefore, the probability  that the outcome we chose will be the outcome of the event is given by

P(A)=\dfrac{n(A)}{n(S)}=\dfrac{1}{10}=0.10.

Thus, teh required probability is 0.10.

Option (B) is CORRECT.

When Victoria goes bowling, her scores are normally distributed with a mean of 130
Artemon [7]

Answer:

0.2377 or about a 23.77% chance

Step-by-step explanation:

P(123<X<130) = normalcdf(123,130,130,11) = 0.2377303466 ≈ 0.2377

Therefore, the probability that the next game Victoria bowls, her score will be  between 123 and 130 is 0.2377 or about a 23.77% chance

A large high school offers AP Statistics and AP Calculus Among the seniors in this school 65% take AP Statistics, 45% take AP Ca
Igoryamba

Answer:

0.8

Step-by-step explanation:

P(AP statistics) = 65%

P(AP Calculus) = 45%

P(AP statistics n AP Calculus) = 30%

Probability of AP statistics or AP Calculus but not both :

Probability of event A or B :

P(AUB) = p(A) + p(B) - p(AnB)

P(AP statistics U AP Calculus) = P(AP statistics) + P(AP Calculus) - P(AP statistics n AP Calculus)

= 0.65 + 0.45 - 0.30

= 0.8

= 80%

(Angle/triangle problem 25points)<br> What is the value of X?
Serhud [2]

Answer:

x = 5

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles in the triangle and equate to 180, that is

10x - 4 + 8x + 3 + 91 = 180

18x + 90 = 180 ( subtract 90 from both sides )

18x = 90 ( divide both sides by 18 )

x = 5
