We want to find the probability that Berenice gets all the answers correct.
<u>1 question:</u>
Each question has 4 options, each option has the same probability of being the correct option, so she has a 25% of<u> randomly selecting the correct option.</u>
Then the probability here will just be equal to the number of correct options (1) over the total number of options (4)
p = 1/4
2 questions:
We already know the probability for one question, then the probability of getting two questions correct will be equal to the <u>product of the individual probabilities</u> for each question:
p = (1/4)*(1/4 = 1/16
3 questions:
Similar approach as before:
p = (1/4)*(1/4)*(1/4) = 1/64
4 questions:
p = (1/4)*(1/4)*(1/4)*(1/4) = 1/256

Answer: 54.29%
Step-by-step explanation:
Given: The probability that they will win both games is 38%.
i.e. P( both games will win) =0.38
The probability that they will win just the first game is 70%.
P(first game will win) = 0.70
To find : P(second game will win| first game will win)
Using formula: 
So, P(second game will win| first game will win) = 
Hence, the required probability = 54.29%
C , i dont know if it’s right but it’s the only table with the same number on the bottom . and same number in general
Answer:
P(A): It is the probability of selecting someone with blue eyes.
: It is the probability of selecting someone who does not have blue eyes
Step-by-step explanation:
We are given the following in the question:
A: event of selecting someone with blue eyes.
Probability:
- The probability of an event tells the chances of happening of that event.
- It is mathematically defined as:
Complement of an event:
- It is the event that consist of all outcomes not happening in A.
- It is represented by
We have to explain the representation:
a) P(A): It is the probability of selecting someone with blue eyes.
It gives us the chances of someone having blue eyes.
b) : It is the probability of selecting someone who does not have blue eyes
It is the chances of selecting someone who does not have blue eyes.
Answer:
The snail will travel 11.75 ft in 5 minutes.
Rule= S(t) = 2.35 t
Explanation:
Since the snail is moving at 2.35 ft per minute, all you have to do is multiply 2.35 by 5 and that's how you get 11.75.
The Rule is the equation that could be used to solve the problem. S represents the snail, and t is how much time the snail travels. To solve from the rule, all you have to do is replace the t in the parenthesis and at the end with a 5 to represent the 5 minutes the snail travels.
Hope this makes sense to you.
