The probability of a football team winning a match is 0.3. the probability of the same football team losing a match is 0.55. what is the probability of the same football team drawing a mathc?

0.15

Step-by-step explanation:

1 -  P winning - P losing = P drawing

1 - 0.3 - 0.55 = 0.15

0.15

Step-by-step explanation:

From the given information it is clear that

Probability of a football team winning a match = 0.3

Probability of the same football team losing a match = 0.55

We need to find the probability of the same football team drawing a math.

We know that the sum of probability of all distinct possible event is 1.

Therefore, the required probability is 0.15.

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
