There are 50 roses in a tray. There is at least 1 red rose among any 24 randomly selected roses, and there is 1 white rose among
VMariaS [17]

So probability of red rose is 1/24

Probability of white rose is 1/28

TOTAL roses= 50

  • P(A)=(1/24)
  • P(B)=1/28=0.035
  • P(AUB)=1/50

P(A$\cap$ B)=1/24+1/28-1/50

  • 175+150-84/4200
  • 241/4200=0.057

So Probability of white is

  • 0.057-0.035
  • 0.022

The product of two consecutive integers is 420. An equation is written in standard form to solve for the smaller integer by fact
gladu [14]

The larger integer is x + 1.

x(x + 1) = 420

x^2 + x = 420

x^2 + x - 420 = 0

The constant is -420.
