Answer:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5
Step-by-step explanation:
350 - 50x = 100
350 - 350 - 50x = 100 -350
50x = 250
50/50x = 250/50
x = 5

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).
