The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

Rolling three dice what is the probability of obtaining at least one six?

50%. There are three dice; each die has 6 faces.


What is the probability of obtaining a sum of at least 6when rolling a pair of dice?

The best way to do this is to note that this is 1 minus the probability of obtaining a sum less than 6. The probability of obtaining a 2 is 1/36 (both dice get 1) The probability of obtaining a 3 is 1/18 (one dice gets 1, the other gets 2, or the other way around) The probability of obtaining a 4 is 1/12 (both dice get 2, or one dice gets 1 and the other 3, or the other way around) The probability of obtaining a 5 is 1/9 (one dice gets 2 and the other 3, or the other way around, or one dice gets 1 and the other 4, or the other way around) Adding these probabilities up gives 5/18. 1 minus this is 13/18 Thus the probability of obtaining a sum of at least 6 when rolling a pair of dice is 13/18.

What is the probability of getting 4 dots on top in rolling two dice?

The probability of rolling a 4 in a die is 1 in 6, or about 0.1667. The probability, then, of rolling a 4 in at least one of two dice rolls is twice that, or 2 in 6, or 0.3333. The probability of rolling a sum of 4 in two dice is 3 in 36, or 1 in 18, or about 0.05556.


Probability of rolling doubles with two dice?

A pair of dice are rolled find the probability at least one dice is a 4?

When rolling one die, the probability of getting a 4 is 1 in 6, or 0.1667. If two dice are rolled, you get two unrelated chances of rolling at least one 4, so the probability is 2 in 6, or 0.3333.
