What is the Probability rolling an odd number?

Mathematics
2 answers:
Keith_Richards [23]3 years ago

Answer:

In this situation, rolling a six-sided has 6 outcomes, each of which is equally likely, so we can define the probability of an event (such as rolling a 3 or rolling an odd number) as the ratio of favorable outcomes to possible outcomes: the probability of rolling a 3 is 16 and the probability of rolling an odd number

Answer:

50%

Step-by-step explanation:

If we are talking about a six-sided die, there are only six outcomes: 1, 2, 3, 4, 5, 6. The only odd number outcomes are 1, 3, 5. To find the probability, we divide the number of desired outcomes by the total number of outcomes.

3/6 = 1/2 = 0.5 = 50%

What is 3 + -5= and is it a positive or negative number and how?
Natalka [10]
It is -2.  This is negative.  For instance, if you had 3 candies and your mother took away 5, you would not only have 0 candies, but you would owe your mother 2.  This is expressed as a negative number.  Please mark Brainliest!!!

How many commuters must be randomly selected to estimate the mean driving time of Chicago commuters? We want 95% confidence that
zimovet [89]

Answer:

61 commuters must be randomly selected to estimate the mean driving time of Chicago commuters.                

Step-by-step explanation:

Given : We want 95% confidence that the sample mean is within 3 minutes of the population mean, and the population standard deviation is known to be 12 minutes.

To find : How many commuters must be randomly selected to estimate the mean driving time of Chicago commuters?

Solution :

At 95% confidence the z-value is z=1.96

The sample mean is within 3 minutes of the population mean i.e. margin of error is E=3 minutes

The population standard deviation is s=12 minutes

n is the number of sample

The formula of margin of error is given by,

E=\frac{s\times z}{\sqrt{n}}

Substitute the value in the formula,

3=\frac{12\times 1.96}{\sqrt{n}}

3=\frac{23.52}{\sqrt{n}}

\sqrt{n}=\frac{23.52}{3}

\sqrt{n}=7.84

Squaring both side,

n=61.4656

Therefore, 61 commuters must be randomly selected to estimate the mean driving time of Chicago commuters.
