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 any 28
randomly selected roses. How many white roses are there? QUICK PLS

Respuesta :

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
