1) You have a bag that contains 5 blue, 3 green, 2 red, and 1 white marble. You select a marble at random. Find each probability.

P(blue)

P(not green)

P(green or white)

P(green, then red when green is replaced)

P(red, then blue when red is not replaced)

See below

Step-by-step explanation:

P(b) = 5/11

p(n g) = 8/11

p(g or w) = 3/11 + 1/11 = 4/11

p(g and r) = 3/11 x 2/11 = 6/121

p(r and b)= 2/11 x 5/10 = 1/11

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
