Answer:
1/5
Step-by-step explanation:
You expect to get 12 red marbles out of 60 trials.
So, you expect to get a red marbles 12/60 of the times.
We can simplify that 12/60 to 1/5, which is a choice of answers. :-)
We assume here you correctly assume your probability level when you did your forecast of 12/60. And either you're picking from a small pool and re-insert the marble, or you have a very large amount of marbles (at least 60).
Answer:
YEAH
Step-by-step explanation:
Answer:
1/6
Step-by-step explanation:
The probability of an event happening k times in n trials if the probability of the event is called p is the binomial distribution probability:
P(k times in n trials) = (Ckn)pk(1-p)n-k where the 1st term is the combination of n things k at a time or
n!/(k!(n-k)!)
In this case n is 100, k is 25 and P = 1/6
