Abag of marbles contains blue (b), red (r), yellow (y), and green (g) marbles. a marble is drawn from the bag, recorded, and then placed back in the bag. estimate the probability the next marble is not red. r y g bo 0.75 o 0.25 o 0.50 o 0.33

Probability that next marble is not red is 0.75

Solution:

Given that bag of marbles contains blue (B), red (R), yellow (Y), and green (G) marbles.

A marble is drawn from the bag, recorded, and then placed back in the bag. To find:  the probability the next marble is NOT red

The probability of an event is given as:

Let us first find the probability of getting red marble

Total number of possible outcomes = blue + red + yellow + green

Total number of possible outcomes = 4

Favorable outcome = getting red marble

Number of favorable outcomes = 1

Finding probability that next marble is NOT red:

P( NOT R) = 1 - P(R)

Thus probability that next marble is not red is 0.75
