That's easy if there is 100 chairs there would be 10 rows with ten chairs in each row
The easiest way to find this answer is to work through it step by step.
She starts with 75 pieces.
She eats 5 pieces, so the # of pieces goes down from 75 to 75-5 = 70.
So she has 70 pieces left to put in the bags.
She puts the same amount in each of 10 bags... so we divide 70 by 10 to find the # of pieces in each bag.
70 divided by 10 is 7.
She put 7 pieces in each bag.
Answer: 0.951%
Explanation:Note that in the problem, the scenario is either the adult is using or not using smartphones. So, we have a yes or no scenario involved with the random variable, which is the number of adults using smartphones. Thus, the number of adults using smartphones follows the binomial distribution.
Let x be the number of adults using smartphones and n be the number of randomly selected adults. In Binomial distribution, the probability that there are k adults using smartphones is given by

Where p = probability that an adult is using smartphones = 54% (since 54% of adults are using smartphones).
Since n = 12 and k = 3, the probability that fewer than 3 are using smartphones is given by

Therefore, the probability that there are fewer than 3 adults are using smartphone is 0.00951 or
0.951%.
