there are six red balls and nine blue balls in a box.a ball is selected at random.find the probability that the ball is (a)red(b) blue ( c) red or blue

There are six red ball and nine blue balls in a box . find the probability that the ball is 1.red 2.blue 3.red or blue 4.yellow

Help me with this question

Thanks

To find the probability of selecting a red ball, we need to determine the number of red balls and the total number of balls in the box.

In this case, there are six red balls and nine blue balls, giving a total of 6 + 9 = 15 balls.

(a) Probability of selecting a red ball:
The probability of selecting a red ball is given by:
Number of favorable outcomes (red balls) / Total number of possible outcomes (total balls)

Therefore, P(red) = 6 / 15 = 2 / 5

To find the probability of selecting a blue ball, we need to use the same approach.

(b) Probability of selecting a blue ball:
The probability of selecting a blue ball is given by:
Number of favorable outcomes (blue balls) / Total number of possible outcomes (total balls)

Therefore, P(blue) = 9 / 15 = 3 / 5

For the probability of selecting either a red or blue ball, we can add the probabilities of selecting a red and blue ball separately.

(c) Probability of selecting either a red or blue ball:
P(red or blue) = P(red) + P(blue)
= 2 / 5 + 3 / 5
= 5 / 5
= 1

So, the probability of selecting either a red or blue ball is 1 or 100%.

Please let me know if I can help you with anything else.

done, look back at your previous post
