Answer:
The probability of 1 or less children from that group to learn how to swim before 6 years of age is 0.072
Step-by-step explanation:
In this case we need to compute the probability of none of these 12 children learns to swim before 6 years of age. This is given by:
p(0) = (1 - 0.312)^(12) = 0.688^(12) = 0.01124
We now need to calculate the probability that one child learns to swim before 6 years of age.
p(1) = 12*0.312*(1 - 0.312)^(11) = 3.744*(0.688)^(11)
p(1) = 3.744*0.01634
p(1) = 0.0612
The probability of 1 or less children from that group to learn how to swim before 6 years of age is:
p = p(0) + p(1) = 0.01124 + 0.0612 = 0.07244

Best Food Store is offering the same size box of
Cocoa Blast at a price of $3.50 for two boxes.
Which offer gives you the most cereal for your
money?
Answer:
The Friendly Food Store's sale.
Step-by-step explanation:
Say you were to get 10 boxes of cereal. We would use this to figure out which one costs less.
Since the Friendly Food Store is offering 5 for 8.25, we would multiply the amount of money by two to get 10.
8.25 x 2 = $16.50
The Best Food Store is offering 2 for 3.50. The same would apply here for the equation, but we would multiply the amount by 5.
3.50 x 5 = $17.50
Thus you would find out that the sale at the Friendly Food Store would give you the most cereal for your money.
