Probability that the sum of the two numbers is greater than 3 but less than 7?
Answers
Answer:
0.4444 = 44.44% probability that the sum of the two numbers is greater than 3 but less than 7.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
A number is selected at random from each of the sets {2,3,4} and {1, 3, 5}.
The possible values for the sum are:
2 + 1 = 3
2 + 3 = 5
2 + 5 = 7
3 + 1 = 4
3 + 3 = 6
3 + 5 = 8
4 + 1 = 5
4 + 3 = 7
4 + 5 = 9
Find the probability that the sum of the two numbers is greater than 3 but less than 7?
4 of the 9 sums are greater than 3 but less than 7. So
0.4444 = 44.44% probability that the sum of the two numbers is greater than 3 but less than 7.

Not a function
Step-by-step explanation:
Each input can have only have one output.
x(1) can't equal both -1 and 3 at the same time.
x(2) can't equal both 4 and 0 at the same time.
x(3) can't equal both 5 and 1 at the same time.
In other words there can't be multiple X's equalling different things.

The probability that the death in 2014 was not caused by heart diseases or Unintentional Injuries = 0.714
= 0.714
Step-by-step explanation:
Let's interpret the question our way ti solve it .
Total deaths in 2014:
2626418
Death caused by Heart Diseases:
614348
Death caused by Unintentional Injuries:
750401
Therefore, we can deduced that, the number of death not caused by Heart Diseases or Unintentional Injuries = Total deaths in 2014 minus sum of the recorded death.
= 2626418 - ( 614348 + 136053)
= 2626418 - 750401
= 1876017.
Now, the probability that there were death in 2014 is 1 (one)
To find the probability that death we're not caused by heart diseases or Unintentional Injuries:
= 1 - Pr (Death Caused by heart diseases) + Pr (Death causes by Unintentional Injuries)
= 1 - (0.234 + 0.052)
= 1 - 0.286
= 0.714
To Check:
= 1876017 / 2626418
Divide to the lowest term
=0.714
The probability that a death in 2014 was not caused by diseases of the heart or unintentional injuries is approximately 0.714 or 71.4%.
Here, we have to find the probability that a death in 2014 was not caused by diseases of the heart or unintentional injuries, we need to subtract the number of deaths caused by these two specific causes from the total number of deaths and then divide it by the total number of deaths.
Total number of deaths in 2014: 2,626,418
Number of deaths caused by diseases of the heart: 614,348
Number of deaths caused by unintentional injuries: 136,053
Number of deaths not caused by diseases of the heart or unintentional injuries = Total deaths - Deaths caused by diseases of the heart - Deaths caused by unintentional injuries
Number of deaths not caused by diseases of the heart or unintentional injuries = 2,626,418 - 614,348 - 136,053
Number of deaths not caused by diseases of the heart or unintentional injuries = 1,876,017
Now, we can calculate the probability:
Probability = Number of deaths not caused by diseases of the heart or unintentional injuries / Total number of deaths
Probability = 1,876,017 / 2,626,418
Probability ≈ 0.714 (rounded to three decimal places)
So, the probability that a death in 2014 was not caused by diseases of the heart or unintentional injuries is approximately 0.714 or 71.4%.
