Answer:
1 / 10 ; 1 / 5 ; 5 / 12 ; 2 / 5
Explanation:
Experimental probability is defined as the ratio of the total number of times an event occur to the total number of trials.
In the experiment performed, the total number of trials is the number of times a paper was drawn from the lot, which 120 times.
From the experiment, the following observations were recorded :
X ___ number of times drawn
1 ____ 12
2 ____18
3 ____ 13
4 ____ 9
5 ____8
6 ____ 24
7 ____ 9
8 ___ 12
9 ___ 8
10 ___ 7
Experimental probability = number of times an event occur / total number of trials
Experimental probability of :
P(1) = 12 / 120 = 1 / 10
P(6) = 24 /120 = 1 / 5
P(an odd) = p(1) + p(3) + p(5) + p(7) + p(9)
P(odd) = (12 + 13 + 8 + 9 + 8) / 120 = 50 / 120 = 5 / 12
A prime number = P(2) + p(3) + p(5) + p(7)
P(prime number) = (18 + 13 + 8 + 9) / 120 = 48 / 120 = 2 / 5
Answer:
true because Unintentional injuries—such as those caused by burns, drowning, falls, poisoning and road traffic—are the leading cause of morbidity and mortality among children in the United States. Each year, among those 0 to 19 years of age, more than 12,000 people die from unintentional injuries and more than 9.2 million are treated in emergency departments for nonfatal injuries.

4.using your muscles
5.using oxygen
When faced with a difficult situation or anxiety always pause yourself, take a deep breath. And examine the situation, make a plan, and take action.
