Students were inquired to answer a question at schools and to say what is most important for them to succeed. Out of the many results, the one which that stood out was practice. Persons who generally are successful do not become successful by being born. They work hard and dedicate their lives to succeeding. This is how you can achieve your goals. as follows are one of the answer and question example that you may utilize to practice and enhance your understanding and also give you insights that might just guide you to maintain your study in school.

## Question:

Based on his past record, Luke, an archer for a college archeny practice L auke wesent the number on his past record, Luke, an archer for a college archery team, has a probability of 0.90 of hitting the inner Assume that in one practice Luke will attempt 5 shots ers. Let the random variable X represent the number of times he hits ring of the target with a shot of the arrow. Assume that each shot is independent from the Let team varable of the arrow and in attempts. The probability distribution of X is given in the table. P(X) 0 000001 0,00045 0.00810 0.07290 03280S 0.59049

What is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X?

(A) 0.40951

(B) 0.50000

(C) 0.59049

(D) 0.91854

(E) 0.99144

## Answer:

**Answer:**

Option (A) 0.40951

**Step-by-step explanation:**

We are **given the following** information in the question:

P(target) = 0.90

Let the random variable X represent the number of times he hits ring of the target with a shot of the arrow.

The **probability distribution** of X is

x: 0 1 2 3 4 5

P(x): 0.00001 0.00045 0.00810 0.07290 0.32805 0.59049

The **mean of discrete probability distribution **is given by:

**Now, we have to evaluate**

**Option (A) 0.40951 t is the probability that the number of times Luke will hit the inner ring of the target out of the 5 attempts is less than the mean of X.**

From the answer and question examples above, hopefully, they are able to guide the student deal with the question they had been looking for and remember of the whole thing declared in the answer above. You would certainly then have a discussion with your classmate and continue the school learning by studying the subject as a group.
