Question

A light can shine blue (B), red (), or yellow (Y) Every second the color changes and is recorded. Estimate the probability the next color will be red. B R Y R R R R Y R B R R

Answer 1

The probability that the next color will be red is:
`(2)/(3)`

Explanation:

The probability of an event is defined as:

Probability=(Total number of favourable outcomes)/(Total number of outcomes )

Here we have to find the probability that the next colour is red is given by:

The recordings are given as:

B R Y R R R R Y R B R R

Number of outcomes that red will come up=8

Total number of outcomes=12

Hence the probability is given by:

`Probability=(8)/(12)=(2)/(3)`
