So, the right option is 1. so if my ans was helpful u can follow me.
Y=-1x+2 I think .................
Using the binomial distribution, it is found that there is a 0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.
<h3>What is the binomial distribution formula?</h3>
The formula is:


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.
Considering that there are 4 questions, and each has 5 choices, the parameters are given as follows:
n = 4, p = 1/5 = 0.2.
The probability that he answers exactly 1 question correctly in the last 4 questions is P(X = 1), hence:


0.4096 = 40.96% probability that he answers exactly 1 question correctly in the last 4 questions.

Answer:
i dont know the other questions but i do know the last one and the answer is rhombus.
A: 
B: grouping
Step-by-step explanation:
We are given the polynomial: 
Part A: What is the correct factorization of
over the integers?
We need to factorize the term 
Factorizing by grouping:




So, factors of the term
are 
Part B: What method is used to factor p(x)=8x3+12x2+2x+3?
The method used to factor the given polynomial is grouping.
We group the terms and then find the common terms in that specific group
So, the answers are:
A: 
B: grouping
