You select four cards from a box with 3 red cards, 5 white cards, and 2 blue cards, and then replace your cards. What is p, the probability of selecting a red card?
What is the probability of failure in a single trial? (q)
What is the number of times a trial is repeated? (n)
What is the the number of successes in the total number of trials? (x's)
Create a probability distribution for the the number of red chips selected from the box. What is P(4) to three decimal places?

Idon’t know actually i’m in 5th grade and don’t know

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
