It's a binomial problem with n = 5, p = 0.12 ; x = 4
P(x=4) = 5C4(0.12)^4(0.88)^1 = 5*(0.00030736)(0.88) = 0.000912384..</span>
Answer: 120
You can do p/100 = is/of
40/100 = is/300
then multiply diagonally which is 40 and 300
divide by 100
or the easier way is you can multiply .4 and 300
Since the discriminant is positive, this means we have two distinct real solutions.
If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.
