Question

If a ball is drawn at random from a box containing 6 red, 4 blue and 5 white balls. What is the probability that the ball drawn is red or blue

Answer 1

Total number of balls = 6 + 4 + 5 = 15

Find the probability of drawing a red ball:

Number of red balls = 6

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

Find the probability of drawing a blue ball:

Number of blue balls = 4

P(Blue) = 4/15

Find the probability that it is a red or a blue:

P(red or blue) = 2/5 + 4/15 = 2/3

Answer: The probability is 2/3

HERE'S THE ANSWER..

______________________________

♠️ It is given that box has

⏺️ 6 red balls , 4 blue and 5 white balls

✔️ So total ball is box is

=> total ball = 6 + 4 + 5 = 15 balls

⏺️ So there are total 15 balls

▶️ We have to find probability of getting a blue or a red ball.

⏺️ Favourable ball = red ball + blue ball

=> favourable ball = 6 + 4 = 10

✔️ Probability = Favourable outcome / total outcomes

=> Probability = 10 / 15

=> $\boxed{ Probability\:= 2 / 3}$

⏺️ So the probability of getting a blue or a red ball is [ 2 / 3 ]
