About Jack Cheng Expertise I can answer most questions in Math up to single-variable Calculus, including infinite series. I like to think very much, so questions with a lot of twists and turns are highly welcomed! Mathematical questions related to computer science are also highly welcomed!
I can also answer some basic questions in discrete mathematics (logics, sets, some algorithms, basic number theory). I am also studying physics (mechanics in particluar), so I am willing to answer some questions relating to it.
Experience Majoring in Mathematics.
Education/Credentials I am sophomore/junior status in college working towards bachelor's degrees in Computer Science and Mathematics.
Question Two balls are taken out at random from a bag containing 6 red and 2 blue balls. Find the probability that just one ball is blue
Answer Hi Hassan,
Probability is a ratio of expected over total possible.
In your problem, the total possible is 6+2 or 8. The expected is a blue ball, in which there are two in the total possible. So the ratio is 2/8 or 1/4.
I am not sure what form your teacher asks, but 1/4 can be changed to 25% or 0.25.
