Answer:
its arung the middle or to thr right
Step-by-step explanation:
Using the binomial distribution, it is found that:
The probability that the student will get 15 correct questions in this test by guessing is 0.0207 = 2.07%.
For each question, there are only two possible outcomes, either the guess is correct, or it is not. The guess on a question is independent of any other question, hence, the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- There are 20 questions, hence
.
- Each question has 2 options, one of which is correct, hence

The probability is:

In which:







Then:

The probability that the student will get 15 correct questions in this test by guessing is 0.0207 = 2.07%.

Answer:
320 Grams of Insects
Step-by-step explanation:
8 Bats = 40 grams
I divided the grams between the bats, so:
40 ÷ 8 = 5
Then Multiplied 5 by 64, which equals 320 grams total for 64 bats.
16 - 6 = 10
2 1/2*4= 10
