You can solve it algebraically by simply adding the numbers in the parenthesis and multiplying to get 35x but if you want to solve it using distributive property exclusively then distribute as so
5x(3) + 5x(4)
15x + 20x
35x
Answer:
55
Step-by-step explanation:
Answer:
1:1
Step-by-step explanation:
They look exactly the same so they would equal each other
Answer:
And we can find the individual probabilities like this:
And adding we got:
Step-by-step explanation:

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:
