Question

A bag, there are 8 red, 7 yellow and 6 green balls. If one ball is picked up at random, what is the probability that it is neither red nor gree

Answer 1

Answer:

7/21

Step-by-step explanation:

since a bag contain 8+7+6 =21 balls.

according to question the ball choosen is neither red nor green it means the only color left is yellow ball.

so we will find the probability of getting yellow ball means niether red nor green

probability=no. of yellow balls/ total no. of balls

=7/21 <------Answer

Answer 2

Answer:

Probability of getting neither red nor green ball = 1/3

Explanation:

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Total number of balls = 21

Neither red or green balls = 21 - (8-6) = 21-14 = 7 balls

possible outcomes = 7

Probability = Possible outcomes/ total number of outcomes

Probability = 7/21

Probability = 1/3
