Question

✳️a bag contains 75 red balls and 25 green balls. a ball is taken out from a bag at random. what is the probability of red and green balls

Solution ⬇️

✍️S={Red ball + Green ball}={75+25}={100}

✍️n(S)=100

➡️Let A be the event of getting Red ball

✍️A={75}

✍️n(A)=75

 =  =   > p(a) =  \frac{n(a)}{n(s)}  =  \frac{75}{100}  = 0.75

➡️Let B be the event of getting Green ball

✍️B={25}

✍️n(B)=25

 = =  > p(b) =  \frac{n(b)}{n(a)}  =  \frac{25}{100}  = 0.25
