Answer:
And we can find the individual probabilities like this:
And adding we got:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
For this case we want to find this probability:
And we can find the individual probabilities like this:
And adding we got:
Answer:
Step-by-step explanation:
Diameter:
from this information we can find the radius of the golf ball:
A golf ball is shaped like a sphere, and the formula for finding the volume of a sphere is:
where r is the radius and is a constant:
we substitute the values of pi and the radius to find the volume:
the closest to the volume of a golf ball:
Answer:
I think that answer is D option
7 and 2 are addents

= equal sign
9 sum
Answer:
C. 800 miles per 16 hours
Step-by-step explanation:
600 ÷ 15 = 40
1500 ÷ 50 = 30
800 ÷ 16 = 50
900 ÷ 20 = 45
40 > 30 < 50 > 45
