1. In a game, if you roll a 2 or a 3 on a 6-sided number cube, you lose a turn. NOTE: This is just using one number cube.

a. What is the probability that you roll a 2 or 3, P (2 or 3)? Explain your reasoning

1/3

Step-by-step explanation:

On a 6-sided number cube, the probability that you roll a 2 is 1/6,

(Remember that the probability equals: Number of positive outcomes/ number of possible outcomes) So you have 1 positive outcome (to roll a 2) among 6 possible outcomes.

This same thinking applies for the case of rolling a 3 and the probability is 1/6.

Now you want to roll either a 2 or 3. In probability, when we get an "or" this means that we have to sum up our probabilities.

Thus, the P(2 or 3) =

Thus the probability of rolling a 2 or 3 is 1/3

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.
