What is 75-50, then you subtract that answer from 180, because if it’s a triangle, all 3 sides should equal to 180
Answer:
- p=0.7103 (4-game series)
- p=0.6480 (2-game series)
Step-by-step explanation:
Let X be the random variable equal the the first 4 straight wins. An overall win for the stronger team implies a negative binomial function with the parameters n=4, p=0.6:

#We find probabilities for the different values of i:

Hence, probability of the stronger team winning overall is:

#Define Y as the random variable for winning 2/3 games.:

Hence, probability of the stronger team winning in 2 out 3 game series is 0.6480
The stronger team has a higher chance of winning in a 4-game series(0.7103>0.6480)
Just multiply directly numerator with numerator and denominator with denominator
Answer:
D: (1, 4)
Step-by-step explanation:
You can either solve by substitution or elimination. If you are timed, the fastest way is to guess and check (plug-in the answer choices)
I will be using substitution to solve this:
Step 1: Since you have y already, you can set them equal to each other
x+3 = 3x+1
3 = 2x +1
2 = 2x
x = 1
Step 2: Now you have x, plug x into one of the original equations. In this case, I will use the first one
y = 1 + 3
y = 4
Step 3: Now write your answer as a coordinate plane point
x = 1, y = 4
(1, 4)
