The top part equals 1 because anything to the power of zero equals one. then for the second one bring every variable with a negative exponent to the top and leave the 2 at the bottom
This problem can be solve using the Binomial Distribution, it is a recurrence conveyance of the conceivable number of effective results in a given number of trials in each of which there is a similar likelihood of accomplishment.
Let be X: coffleton residents recognize the brand name
n = 10
p = 0.53
q = 0.47
P(X = 4) =
(10)
(4)*(0.53^4)*(0.47^6) = <span>0.00340</span>
At least 3. Have a nice day! :)
