Answer:
tasha got 1/2 of it
one friend got 1/4 of it
the other friend got 1/4 of it
Step-by-step explanation:
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.

100 is ten times as much as 1/10 of a hundred
ur multiplying n then dividing by ten so they cancel each other out
theres no table so idk if this is what u wanted but that's the answer
hope it helps
I will give u the steps
add up all of the values
then when you find the total lets say its 100% then total percent of cars would be 32%
