Answer:
0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Determine the probability that at least one color will be missing from the 10 selected balls.
Red missing:
Each time, there are 55 + 25 = 80 non-red balls, out of 100. So, in each of the 10 trials, 80% = 0.8 probability of not picking a red ball. The probability that no red ball is picked is given by:
(0.8)^10 = 0.1074
White missing:
55 + 20 = 75 non-white balls, out of 100, in each trial. The probability that no white ball is picked is given by:
(0.75)^10 = 0.0563
Blue missing:
45 non-blue balls, out of 100. The probability that no blue ball is picked is given by:
(0.45)^10 = 0.0003
Total:
0.1074 + 0.0563 + 0.0003 = 0.164
0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.
The worst case is when you pull 4 out and have 4 different colors. the 5th sock MUST match one of these. 5 is the answer
Hi,
to find out the answer you need to divide 89 by 10 than by 5. Add those two answers together which is 23.73. That answer is dimes so 89-23.73=65.27..:) you could round the number up. I hope it helps!!!
To find this out first we will see how many cars they assemble in 1 hour. Lets do it:-
150 / 3 = 50
50 cars per hr
50 * 8 = 400
400 cars in 8 hrs
CHECK OUR WORK;-
400 / 8 = 50
We were RIGHT!!
So, in 8 hrs the factory can assemble 400 cars.
Hope I helped ya!! xD
