The probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.
What is probability?
It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
We have the probability P(R) of randomly removing a red bead is 20%.
Let's suppose the number of red beads is n(R)
[tex]\rm P(R) = 20\% \Rightarrow 0.20\\\\\rm \frac{n(R)}{15} = 0.20[/tex]
n(R) = 15×0.20
n(R) = 3
Number of yellow beads = 15 -3 = 12
The probability randomly removing a yellow bead:
[tex]=\rm \frac{12}{15}[/tex]
= 0.8 or 80%
Thus, the probability of randomly removing a yellow bead is 0.8 or 80% if the bag contains 15 beads that are either red or yellow the probability of randomly removing a red bead is 20%.
