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".
Solution to the problem
Let X the random variable of interest (number of children that may have a blood level that may impair development), on this case we know that:
Since we select a sample of 10 and the probability of success for each trial is 0.6
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want to find this probability:

Equation of rockets height is given by
Height will be zero once the rocket lands on the ground
So, we can write
Answer:
Length: 6, Width: 2
Step-by-step explanation:
6 times 2 is 12 and 6 + 6 + 2 + 2 = 16.
Hey there! :)
To find mean, you have to add all the numbers and divide it by how many numbers there are.
70 + 68 + 72 + 66 + 68 + 69 + 66 + 71 + 74 + 66 = 690
There are 10 numbers
690 ÷ 10 = 69
Mean ⇒ 69
