Answer 1

It's incorrect

The answer is choice C and here's why

there are 6 sides to a die (singular for "dice) with the values 1 through 6 on the faces

if you make let the faces with `5` and `6` on them represent "success" then 2 out of the 6 cases are successes

so 2/6 = 1/3 is the probability of success. Rolling the die 10 times is the act of performing 10 trials or random events.

Answer 2

the other answer choices have different probabilities of success

choice A) 1 color a success out of 4 total ----> 1/4 is the probability when we want 1/3 instead. So choice A is out

choice B) 2 digits out of 10 are successes, so 2/10 = 1/5 is the probability when we want 1/3 instead. So choice B is out

Choice D) 50+50 = 100 beads total. Yellow is a "success" so 50/100 = 1/2 is the probability of success, but again we want 1/3 instead. So choice D is out
