No, i don't think so
In a function, one value of x is only assigned to one value of y
It's okay if you can get the same y value from two x value, but that mean that inverse can't be a function.
y = x^2 is a function
but inverse y = +/- √x is not
For the first digit, you have 4 choices (2, 4, 6, 8); for the second and third digits, you have 5 choices (2, 4, 6, 8 and 0). So the total number of positive qualifying numbers is 4*5*5 = 100
The probability that at least 8 patients show improvement is; 0.94
<h3>How to use Binomial Probability Distribution?</h3>
The formula for Binomial Probability Distribution is;
P(X = r) = nCr * p^(r) * (1 - p)^(n - r)
where;
n = number of trials
r = number of specific events you wish to obtain
p is probability of success
From the question, we have;
n = 12
r = 8
p = 81% = 0.81
The probability that at least 8 patients show improvement is expressed as;
P(X ≥ 8) = P(X = 8) + P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12)
Using online binomial probability calculator gives us;
P(X ≥ 8) = 0.11954 + 0.22649 + 0.28967 + 0.22453 + 0.07977
P(X ≥ 8) = 0.94
