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

If sin theta = cos theta then find the value of theta
Ksenya-84 [330]

Step-by-step explanation:

\because \sin  \theta =  \cos  \theta  \\   \\ \therefore \: \sin  \theta =  \sin(90 \degree -   \theta)  \\   \\ \therefore \:  \theta =  90 \degree -   \theta \\   \\ \therefore \:   \theta + \theta=  90 \degree \\  \\ \therefore \:  2\theta =  90 \degree \\  \\\therefore \:  \theta =   \frac{90 \degree }{2} \\  \\ \huge \orange{\boxed{\therefore \:   \theta =   45 \degree}}\\  \\
