What is the chance of rolling a number above 3 on a dice?
Six side dye. Let x be the random variable, x ={1, 2, 3, 4, 5, 6). The probability for any of the six possible outcomes is P(x) = 1/6. This gives a flat probability distribution.The probability that the outcome in the rolling of one dye is 3 or a smaller number(2 or 1) is; P(x≤3) = P(x=3) + P(x=2) +P(x=1) = 1/6 + 1/6 + 1/6 = 3/6 = 1/2The probability of the complementary event, that the resulting event is a number above 3 is: P(x>3) = 1 - P(x≤3) = 1 - 1/2 = 1/2 = 0.50 = 50%

How do you evaluate p6 if p equals 3?
When two characters are next to each other (like p6) this means multiplication. Therefore it can be written as p x 6. If you substitute p for 3 you have 3 x 6 which equals 18.
What binomial is a factor of this trinomial x2 plus 13x plus 4?
x2 + 13x + 4 = (x + 6½ + √38¼)(x + 6½ - √38¼). To find this, we need to find p and q, where p + q = 13, pq = 4. 4 = 42¼ - 38¼ = (6½ + √38¼)(6½ - √38¼); thus, p = (6½ + √38¼), q = (6½ - √38¼).
What is the surface area of the prism where B equals 8 m P equals 3 m H equals 6 m?
If B, P, and H are three dimensions ofa rectangular prism them surface area equals 2 x 8 x 3 + 2 x 3 x 6 + 2 x 8 x 6 which equals 180 square meters.
What is the percent of 30.00?
6. all you have to do is use the IS over OF strategy. IS 20% and OF 30 so: P 20 30 100 then cross multiplication: P x 100 = 30 x 20 P x 100/100 = 600/100 P = 6 So there you have it, P = 6

What is the perimeter of a rectangle if the area is 36?
24 ============================= Another contributor took issue: You can't tell. There are an infinite number of rectangles with different perimeters that all have the same area. Here are a few with areas of 36: 1 x 36 . . . . . P = 74 2 x 18 . . . . . P = 40 3 x 12 . . . . . P = 30 4 x 9 . . . . . . P = 26 5 x 7.2 . . . . P = 24.4 6 x 6 . . . . . P = 24

Find the requested value If p x equals 20x5 - 20x4 plus 24x2 and q x equals 4x2 find p over q x?
p x = 20 x5 - 20 x4 + 24 x2 q x = 4 x2 p = 20 x4 - 20 x3 + 24 x, if xis not equal to 0 p / qx = ( 20 x4 - 20 x3 + 24 x) / (4 x2) = (5 x4 - 5 x3 + 6 x) / x2 So p / qx = 5 x2 - 5 x + 6/x if x is not equal to 0
What binomial is a factor of this trinomial x2 plus 13x plus 4?
x2 + 13x + 4 = (x + 6½ + √38¼)(x + 6½ - √38¼). To find this, we need to find p and q, where p + q = 13, pq = 4. 4 = 42¼ - 38¼ = (6½ + √38¼)(6½ - √38¼); thus, p = (6½ + √38¼), q = (6½ - √38¼).
What equals x in this epuation x divided by 7 equals 6?
ok im gonna show you how this works! :P x/7=6 x/7x7=6x7 x=42
When two dice are thrown let X be the larger of the two numbers on the two throws find the probability distribution mean and variance of X?
The probability distribution is P(X = 1) = 1/36 P(X = 2) = 3/36 P(X = 3) = 5/36 P(X = 4) = 7/36 P(X = 5) = 9/36 P(X = 6) = 11/36 P = 0 otherwise. Mean(X) = 4.4722 Variance = 1.9715
A student takes a 10 question multiple choice exam and guesses on each question Each question has five choices What is the probability of getting at least 6 correct out of the ten questions?
By guessing, the probability of getting at least 6 correct is 62201/9765625 which is approx 0.0064 or 0.64 % Using the binomial theorem of: (p + q)^n = Σ nCr p^r q^(n-r) with r = 0, 1, ..., n Each term gives the probability of r successes P(r) out of n trials: p is the probability of success and q = 1 - p is the probability of failure for each trial; for this question: p = 1/5 q = 4/5 n = 10 and to get the probability of at least 6, P(≥ 6) is the sum P(6) + P(7) + P(8) + P(9) + P(10) which is: 10C6 p^6 q^4 + 10C7 p^7 q^3 + 10C8 p^8 q^2 + 10C9 p^9 q^1 + 10C10 p^10 q^0 = 210 x (1/5)^6 x (4/5)^4 + 120 x (1/5)^7 x (4/5)^3 + 45 x (1/5)^8 x (4/5)^2 + 10 x (1/5)^9 x (4/5)^1 + 1 x (1/5)^10 x (4/5)^0 = (210 x 1^5 x 4^4 + 120 x 1^7 x 4^3 + 45 x 1^8 x 4^2 + 10 x 1^9 x 4 + 1 x 1^10) x (1/5)^10 = 62201/9765625 ≈ 0.0064 = 0.64 %
