1. find the probability of this set of independent events. rolling a six on the first roll of a 1-6 number cube and rolling an odd number on the second roll of the same cube 2. find the probability of this set of independent events. drawing a 1, 2, or 3 from 9 cards numbered 1-9, replacing the card, and drawing a 7, 8, or 9 3. a bag contains 3 blue marbles and 2 green marbles. what is the probability of drawing a blue marble followed by a green marble, without replacing the first marble before drawing the second marble?

For the first question, the chance of rolling a six is a 1/6 chance because there is one six and six different sides that could be rolled. As a percent, it would be 16.6 %. The probability of rolling an odd number on the second roll would be a 3/6 chance, which as a percent is 50 %. For the second question, both probabilities are 33 % because in both instances you are drawing three cards from nine total, so it would be 3/9. For the third question, the probability of drawing a blue marble is 3/5, because there are three blue marbles and five total marbles. As a percent, this is 60 %. Following this up with a green marble would be 2/4, because there are now 2 green marbles and four total marbles. One of the marbles was not replaced, so we have one less marble. 2/4 as a percent  is 50%.

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
