Answer:
The probability is 0.27
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem, we have that:
Odds of a win are 27 to 73.
This means that for each 27 games that you are expcted to win, you are also expected to lose 73.
So
Desired outcomes:
27 wins
Total outcomes:
27 + 73 = 100 games
Probability
Answer:
The probability is 0.27
Answer:
The probability that Leon strikes is greater than Carlton strike is 0.40905
Step-by-step explanation:
From the question, we have;
The percentage of Carlton's rolls are strikes, = 70%
The number of games Carlton played, n₁ = 25
The percentage of Leon's rolls that are strikes, = 67%
The number of games Leon played, n₂ = 25
Therefore, we have;
Where;
k₁ = 0.7 × 25 = 17.5
k₂ = 0.67 × 25 = 16.75
The test statistic is given as follows;
From the z-table, we have;
The p-value for Carlton strikes is greater than Leon's strike = 0.59095
∴ The p-value for Leon strikes is greater than Carlton strike = 1 - 0.59095 = 0.40905
The probability that Leon strikes is greater than Carlton strike = 0.40905
Answer:
84.9%
Step-by-step explanation:
First we need to calculate the total number of people. Total number of people will be the sum of all the given frequencies of all classes. There are 9 classes in total that are shown on the histogram
So,
Total number of people = 40 + 40 + 35 + 35 + 25 + 25 + 25 + 25 + 15 = 265
Now we need the number of people who took less than 40 seconds. This will be equal to sum of all frequencies below the time 40 seconds. i.e.
Number of people who took less than 40 seconds = 40 + 40 + 35 + 35 + 25 + 25 + 25 = 225
Formula to calculate percentage is:
So, percentage of people who took less than 40 seconds =
Thus, 84.9% of people took less than 40 seconds to complete the task.
