Question

A bag contains 2 green 3 red and 4 black balls. A ball is taken out of the bag at random.find the probability that the selected ball is 1)Not green 2)not black .

Answer 1

Step-by-step explanation:

not green means red or black

red = 3

black= 4

total balls= 2+$+4= 9

so 1) 3+4/9 = 7/9

not black means green or red= 2+3=5

so. 2) 5/9

Answer 2

Answer:

1) Probability that the selected ball is not green = $\frac{7}{9}$

2)Probability that the selected ball is not black=$\frac{5}{9}$

Explanation:

From the question, we have

Total balls= 2+3+4= 9

Probability that the selected ball is not green

=$\frac{3+4}{9} = \frac{7}{9}$

Probability that the selected ball is not black

=$\frac{3+2}{9} = \frac{5}{9}$

Probability:

Possibility is referred to as probability. This branch of mathematics deals with the occurrence of a random event. The value's range is 0 to 1. Probability has been applied into mathematics to predict the likelihood of different events. Probability generally refers to the degree to which something is likely to occur. This fundamental theory of probability, which also applies to the probability distribution, can help you comprehend the possible outcomes for a random experiment. Gonna determine how likely something is to occur, use probability. Many things are hard to predict with 100% certainty. We can only anticipate the possibility of an event occurring using it, or how likely it is.
