What is the difference between independent and dependent probability?
Select 2 cards, do not put the 1st back in the deck. This is dependent probability. The outcome of drawing the 2nd card depends on the 1st card drawn. Select a card, look at it and put it back in the deck. Select a 2nd card. These are independent of each other. One does not change the probability for selecting the 2nd.
3 purple 2 orange and 5 green what is the probability of drawing the 1st and then the 2nd of purple?
It is 1/15.
When a two dice is rolled what is the probability the two number will have a sum of 8?
5/36 Out of the 36 possible and equally-probable outcomes (1st die's number and 2nd die's number), 5 combinations give you a sum equal 8: * 1st die gives a 2 and 2nd die gives a 6 * 1st die gives a 6 and 2nd die gives a 2 * 1st die gives a 3 and 2nd die gives a 5 * 1st die gives a 5 and 2nd die gives a 3 * 1st die gives a 4 and 2nd die gives a 4 Therefore the probability that the sum is greater than 10 equals 5/36.
A class of 14 boys and 11 girls. What is the probability of selecting a girl 1st and then a girl 2nd and then a boy third.?
Assuming the choices are made randomly and that the chosen people are not returned to the class, the probability is 77/690 = 0.1116 approx.
When two balanced dice are rolled there are 36 possible outcomes what is the probability that the sum of the numbers on the dice is greater than 10?
Out of the 36 possible and equally-probable outcomes (1st die's number and 2nd die's number), only 3 combinations give you a sum greater than 10: * 1st die gives a 5 and 2nd die gives a 6 * 1st die gives a 6 and 2nd die gives a 5 * 1st die gives a 6 and 2nd die gives a 6 Therefore the probability that the sum is greater than 10 equals 3/36, or 1/12.

In one town 61 percent of adults have health insurance What is the probability that 8 adults selected at random from the town all have health insurance?
.61 ^ 8 = .0191707... = 1.92% And an informal proof/explanation: P(A and B) = P(A) * P(B), which means the probability of A and B = Probability of A times the probability of B. P(1st person and 2nd person) = P(1st person) * P(2nd person) P(1st person and 2nd person and 3rd person) = P(1st person) * P(2nd person) * P(3rd person) ... P(1st person) = P(2nd person) = ... = P(8th person) P(1st-8th people) = P(1st) * P(2nd) * ... * P(8th) = P(1st person) ^ 8 .61 ^ 8 = .0191707... = 1.92%

If 10 tickets were sold to you and a friend each bought 1 ticket Two winners will be selected What is the probability that your friend will be selected as 1st prize winner and you as second?
If 10 tickets are sold, and you and a friend buy 1 ticket each. Two winners will be selected. The probability that your friend wins 1st prize and you second prize is: P(event that friend wins 1st and you 2nd) = 1/10 x 1/9 = 0.01111... ≈ 1.11 % The probability that you win 1st and your friend 2nd is the same: P(event that you win 1st and friend 2nd) = 1/10 x 1/9 = 0.01111... ≈ 1.11 % The probability that you and your friend win either way is the sum of both: P(event that you and your friend win either prize) = 0.02222... ≈ 2.22 %

When two balanced dice are rolled there are 36 possible outcomes what is the probability that the sum of the numbers on the dice is greater than 10?
Out of the 36 possible and equally-probable outcomes (1st die's number and 2nd die's number), only 3 combinations give you a sum greater than 10: * 1st die gives a 5 and 2nd die gives a 6 * 1st die gives a 6 and 2nd die gives a 5 * 1st die gives a 6 and 2nd die gives a 6 Therefore the probability that the sum is greater than 10 equals 3/36, or 1/12.
