You roll a standard number cube. find p(number greater than 2).

A standard number cube goes from 1 to 6. Since we are looking for P, the probability of a number greater than 2, we will count how many numbers on the dice are greater than 2.
3, 4, 5, 6. There is 4 numbers out of 6 total.
Your probability is 4/6 or 2/3 if simplified.
I hope this helps!

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.
