at random. What is the probability that the ball drawn is -
(1) red. (2) not red (3) either red or white.​

Answer 1

Answer:

1. 1/3 = 33% 2. 2/3 = 66% % 3. 2/3 = 66% %

Step-by-step explanation:

1

Number of successful outcomes/ Total outcomes = 3/9 = 1/3 = 33%

2

Number of successful outcomes/ Total outcomes = 6/9 = 2/3 = 66%

3

Number of successful outcomes/ Total outcomes = 6/9 = 2/3 = 66%

Answer 2

Answer:

1 .Probability of the ball being red= no.of red balls ÷ total no.of balls

Step-by-step explanation:

probability of red ball=3 ÷ 9 =1/3
