A box contains red and blue beads. 16 out of them are red. If the probability of getting a red bead is $\frac{2}{3}$, a What is the total number of beads ? b What is the probability of getting a blue bead? c If 4 red beads are removed from the box, what is the probability of getting a red bead?
Explanation
Let's denote the total number of beads as x. The probability of getting a red bead is 2/3, so the number of red beads is (2/3)x. We know that the number of red beads is 16, so (2/3)x = 16. Solving for x, we get x = 24.
