SOLUTION: One in five adults have outstanding traffic fines. If seven adults are randomly selected calculate the probability that 3 have outstanding fines
Hi,
One in five adults have outstanding traffic fines. p = .2
If seven adults are randomly selected, P(x = 3)
Using TI Calculator: The syntax is binompdf(n, p, x-value).
P(x=3) = binompdf(7, .2, 3) = .05120 0r 5.12%
