A bag contains 7 red marbles, 2 blue marbles, and 1 green marble. If a marble is selected at random, what is the probability of choosing a marble that is not blue? 7 red marbles plus 1 green marble = 8/10 = answer = 4/5

I do not know how to figure out his next shot. A basketball player has made 34 of her last 42 freethrow attempts. What probability would you assign to the player’s next free throw being successful? Explain your reasoning. 34/42 = 17/21 I would assume that that the basketb...

consider a bowl containing 36 different slips of paper. Ten of the slips of paper each contain one of the set of digits 0 through 9 and 26 slips each contain one of the 26 letters of the alphabet. Determine the probabilities of the events specified. Drawing one slip, what is P...

Does this mean that we do not count the two red fives as they would already be counted in the reds.

Math Probability
consider the experiment of selecting a card from an ordinary deck of 52 playing cards and determine the probability of the stated event. A red card or a card showing a 5 is drawn. There are 26 red cards and 2 extra fives. Would my answer be 28/52?

Probability math ?
If I am rolling a single dice what is the probability of rolling a number that is divisible by 2 and 3? The only number divisible by 2 and 3 is 6. So, would the answer be 1 out 6 or 1/6

Math
I think I confused myself. I do not want to calculate range but variance. In order to get the variance what do I do?

Math
I think, but how about this: calculate range: -1, 0, 1, 0, -1, 0, 1, 0, -1, 0, 1, 0 is it: 1, 0, 1, 0, 1, 0 , 1, 0, 1, 0, 1, 0: but how do you do the rest if this is right?

Math
I do not understand how to figure this out: Calculate variance:
