in a box there are 4 red 3 blue 5 green balls one ball is picked up randomly what is the probability that it is neither red or green

Answer 1

there is a total of 12 balls in the box

4 red 3 blue and 5 green

if they picked up a random ball the probability that it is red or green is 9/12

but both 9 and 12 are divisible by 3

so your final answered should be 3/4

hope this helps :)

Answer 2

Answer:-

• Given:-

Number of red balls = 4

Number of green balls = 5

Number of blue balls = 7

_____Find_____

The probability that it is neither red nor blue.

• Solution:-

Total number of balls in the bag = 4 + 5 + 7 → 16

Probability= No.ofexperiments

Totalno.ofoutcomes

• Probability of red ball = 4/16 = 1/4

• Probability of green ball = 5/16 = 5/16

• Probability of blue ball = 7/16= 7/16

Event that the ball is neither red nor blue = Event that the ball will be green

→ Probability = 5/16
