the probability of rolling a 3 or 4 is 1/3 if you roll a die 270 times, about how many times would you expect to roll a 3 or 4?

Answer 1

To find the expected number of times you would roll a 3 or 4, you can multiply the probability of rolling a 3 or 4 by the number of times you are rolling the die.

Expected number of times = (1/3) * 270 = 90

Therefore, you would expect to roll a 3 or 4 about 90 times if you rolled a die 270 times.
