Answer:
Using the pmf we can find the individual probabilities like this:
And replacing we got:
Step-by-step explanation:

Let X the random variable that represent the number of people that will become sereiosly ill in two years. We know that
The probability mass function for the random variable is given by:
And f(x)=0 for other case.
For this case the value for would be:
For this distribution the expected value is the same parameter
On this case we are interested on the probability of having at least two chocolate chips, and using the complement rule we have this:
Using the pmf we can find the individual probabilities like this:
And replacing we got:
24:N=30:100
Multiply 24 by 100 then divide the product by 30. You'll get the answer which is 80.
12,000
Underline the number in the ten thousands place
look to the right
if number is greater than 5
add 1 to the underlined number
leave the numbers behind the underlined number zero

The correct answer is C on edgen 2021
Step-by-step explanation:
I legit just took a lucky guess and got it right lol
The greatest common factor would be 3 as 15/3 = 5 and 27/3 = 7, cannot get simpler than that!!
