Ah.
I’m stupid and brain dead right now
Answer:
80
Step-by-step explanation:
The three angles of a triangle add to 180 degrees. One angle is 10, the second is a right angle( which is 90 degrees). Let the third angle be x
10 +90 +x = 180
Combine like terms
100 +x =180
Subtract 100 from each side
100-100 +x= 180-100
x = 80

Step-by-step explanation:
Answer:
Not binomial: the trials are not independent.
Step-by-step explanation:
Binomial distribution:
In samples with replacement, as the probability has to be the same for each trial, that is, they are independent.
Hypergeometric distribution:
Samples without replacement, as the probabilities depends on the previous outcomes, that is, they are not independent.
In this question:
Marbles are chosen without replacement, which means that for each trial the probabilities of choosing a red marble are different, which means that the trials are not independent. So the answer is:
Not binomial: the trials are not independent.
