If Katrina rolled a standard die 57 times during one of her math stations. How many times could Katrina predict rlling a 2 or a 6?
To find out how many times Katrina could predict rolling a 2 or a 6, we need to determine the probability of rolling a 2 or a 6 on a standard die and then multiply it by the number of times she rolled the die.
In a standard die, there are 6 equally likely outcomes – numbers 1, 2, 3, 4, 5, and 6. Out of these, 2 and 6 are the desired outcomes. Therefore, the probability of rolling a 2 or a 6 on a standard die is 2/6 or 1/3.
To find how many times Katrina could predict rolling a 2 or a 6, we multiply the probability (1/3) by the number of times she rolled the die (57):
(1/3) * 57 = 19
Therefore, Katrina could predict rolling a 2 or a 6 approximately 19 times when rolling a standard die 57 times.
