Answer:
9/22 or 40.9%
Explanation:
Probability describes the likelihood of an event. To find simple probability, like in this question, use division.
To find the probability of the first question being a free response, you first need to find the total number of questions. This can be done by adding together all of the given information. There are 10 multiple choice, 3 essays, and 9 free responses.
This means that there are 22 total questions. Next, find how many of these questions are free-response. We know that there are 9 free responses and 22 questions in total. So, 9 out of 22 are free responses. This can be rewritten as 9/22.
If you want to find the percentage, simplify the fraction and convert it to a percentage.
Then, move the decimal 2 places to the right. This gives you 40.9%, which is the probability of the first question being a free-response.

I don't know what you are not the things I y you have any other person use it helps I try my god I love you too and that is the story of
Answer:
I think it is 45
n = number of rolls = 150
p = probability of rolling a “1” = 0.3
n*p = expected number of “1”s that show up out of the 150 rolls
n*p = 150*0.3
n*p = 45
