Answer:
And using the probability mass function we got:
Step-by-step explanation:
Previous concepts
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, 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:
And we want to find this probability:
And using the probability mass function we got:

4.5 only. get rid of your 15 answer
Step-by-step explanation:
why the heck are they staying there are two values for X?
this is WRONG. There is one value for X, and 3 triangles to choose from.
Answer:
Y = 50
Step-by-step explanation:
Solve for Y:
Y - 9 = 41
Add 9 to both sides:
Y + (9 - 9) = 9 + 41
9 - 9 = 0:
Y = 41 + 9
41 + 9 = 50:
Answer: Y = 50
Answer:
Mrs. Conner need to prepare 16 batches of banana pudding at party.
Step-by-step explanation:
Given:
Mrs Conner plans to serve banana pudding and she plans to make 2 batches for every 9 people attending.
So it means that p people would get 2 batches of banana pudding.
9 people would get = 2 batches
Number of people who are attending the party is 79
We need to find the number of batches Mrs Conner needs to prepare.
If,
9 people would get = 2 batches
72 people would get = Number of batches need to prepare.
So we will use cross multiplication method to find the same.
Cross multiplying means We need to multiply 2 and 72 and 9 and Number of batches we need to prepare.
Hence we get
Number of batches need to prepare =
Hence Mrs. Conner need to prepare 16 batches of banana pudding at party.
