How did you get that as an answer ?
Answer:
I guess this is the answer
There are a total of 8 balls
The probability of drawing a white ball is 4/8 on the first draw.
If you replace the ball then the probability will still be 4/8 for a white ball, since these events are independent of each other you multiply 4/8 x 4/8 = 16/64 or 1/4 then the probability of drawing at least 1 red ball with replacement is 1 - 1/4 = 3/4
Now without replacement:
the probability of drawing a white ball is 4/8 since you don't replace the ball then the probability of drawing a white ball the second time is 3/7 again multiply these two probabilities: 4/8 x 3/7 = 12/56 the the probability of drawing at least 1 red ball is 1- 12/56 = 44/56 or 11/14
Answer:
3 hours 47 minutes
Step-by-step explanation:
It takes 30 minutes to get from 11:30 am to 12:00 pm, and 3 hours and 17 minutes to get to 3:17 pm from 12:00 pm. There are 60 minutes in a hour.
