What is the probability of getting a 4 or a 6 when a die is thrown together? a) 2/3 b) 1/3 c) 3/6 d) 4/6

Description : What is the probability of getting a 4 or a 6 when a die is thrown together? a) 2/3 b) 1/3 c) 3/6 d) 4/6

Last Answer : Answer: B) Taking the individual probabilities of each number, getting a 4 is 1/6 and so is getting a 6. Applying the formula of compound probability, Probability of getting a 4 or a 6, P(4 or 6) = P(4) + P(6) – P(4 and 6) ==> 1/6 + 1/6 – 0 2/6 = 1/3

What is the probability of rolling a five on one die times in a row?

Description : What is the probability of rolling a five on one die times in a row?

Last Answer : Since there are 6 sides to the die, the probability of rolling a5 on one roll is 1/6. Since each roll is an independent event theprobability of the multiple results is the product of theprobability of each result. So 2 consecutive 5's would occur with aprobability of (1/6)(1/6) = 1/36
