Step-by-step explanation:
There can only be two outcomes. Either a woman has breast or ovarian cancer, or she hasn't. So we can solve this problem by the binomial probability formula.
Binomial probability
Th binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this problem
We want to find P(X = 1), so .
There are 5 woman, so
There is a 51% probability that a woman with this gene has cancer, so
3(n-8)
You make it so that the three is on the outside of the brakets and that you can FOIL to bring it back to how it used to be
Using the Pythagorean theorem:
a^2 + b^2 = c^2 ( a and b are the sides and c is the diagonal)
59.5^2 + b^2 = 70^2
Simplify:
3540.25 + b^2 = 4900
Subtract 3540.25 from both sides:
b^2 = 1359.75
Take the square root of both sides:
b = 36.874
Rounded to the nearest tenth = 36.9 inches.
