Answer:
So then the probability that the batch would be accepeted is:

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:

On this case p=0.04 represent the probability that a random the tablet would be NOT accepted
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
They accept the batch if there is only one or no tablet that doesn’t meet the test specification, so let's find the individual probabilities for this case:
So then the probability that the batch would be accepeted is:

Answer:
What expressions are equivalent to 20
Step-by-step explanation:
since you didn't .show a link this is my guess, i guess.
4x5=20
X - Ollie's age
8 is subtracted from Ollie's age = x-8
the result is the same as
subtracting 16 from 3 times his age = 3x-16

Ollie is 4 years old.
Answer:
The third one
Step-by-step explanation:
solution:
The variable is discrete because it is countable.
The number5 of lightning strikes in a city in one year is countable value.
So, it is discrete
