75/4 = 18.75mm
Answer:
Step-by-step explanation:
There are a total of 10 balls in the first bag, so P(1 red) = 3/10 and P(1 green) = 7/10.There are a total of 9 balls in the second bag, so P(2 red) = 4/9 and P(2 green) = 5/9.P(1 red & 2 red) = 3/10 × 4/9 = 12/90 = 2/15P(1 red & 2 green) = 3/10 × 5/9 = 15/90 = 1/6P(1 green & 2 red) = 7/10 × 4/9 = 28/90 = 14/45P(1 green & 2 green) = 7/10 × 5/9 = 35/90 = 7/18
I hope you understand it!
Answer:
-3/5x + y = - 26/5
Step-by-step explanation:
First, I put everything in slope-intercept form, just because it's more simple for me.
y = 3/5x + b
Since we don't have b, we can use the coordinate they give us to solve for it.
-4 = 3/5 (2) + b
-26/5 = b
y = 3/5x - 26/5
Now, we can move the variables around to fit the form:
Ax + By = C
-3/5x + y = - 26/5
I hope this helped!
Answer:
The probability of no correct answers is 0.125 = 12.5%.
Step-by-step explanation:
For each question, there are only two possible outcomes. Either it is answered correctly, or it is not. The probability of a question being answered correctly is independent of any other question, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
3 trials, each with probability of success (correct) given by p=0.50.
This means that 
The probability of no correct answers is
This is P(X = 0).


The probability of no correct answers is 0.125 = 12.5%.
