what is the probability of rolling a 2,3, or 6 on a regular six sided die?
Since the number of choices or outcomes is six each “roll” of the die falls on either 1,2,3,4,5 or 6. That is, each roll has a probability of 1/6
We want to find, P( 2 or 3 or 6)
P(2 or 3 or 6)
= P(2) + P(3) + P(6)
= (1/6) + (1/6) + (1/6)
= 3/6
= 1/2
=> P(2 or 3 or 6) = 1/2 = 0.5
Probability = 1/2 = 0.5
what is the probability of rolling a 2,3, or 6 on a regular six sided die?
what is the probability of rolling a number greater than 6 on a regular six-sided die?
what is the probability of rolling a number greater than 1 on a regular six-sided die?
A regular six-sided die is rolled 9 times. What is the probability of getting a 1 or 6 on exactly 7 of those rolls?
Sally is rolling a fair 6-sided die. What is the probability that it takes 4 rolls for her to get a six? 0.5787 0.005 0.5177 0.096 0.1667
Suppose you toss a six-sided die 10 times. What is the probability of never rolling a 4?
Suppose you toss a six-sided die 10 times. What is the probability of never rolling a 3? Round to four decimal places.
what is the probability of rolling a number less than or equal to 6 on a regular six-sided die?
Suppose you are rolling a fair four-sided die and a fair six-sided die and you are counting the number of ones that come up. What is the probability that both die roll ones? What is the probability that exactly one die rolls a one? What is the probability that neither die rolls a one? What is the expected number of ones? If you did this 1000 times, approximately how many times would you expect that exactly one die would roll...
