Answer:
69.5%
Step-by-step explanation:
If the original value is 1, the value after the crash is 1-0.41 = 0.59. We want to find the multiplier x so that ...
0.59x = 1
x = 1/0.59 ≈ 1.6949
The percentage increase required is (x -1)×100% ≈ 69.49%.
The stock would have to rise about 69.5%.
Answer:
0.070
Step-by-step explanation:
Y = number on trial
Y has a negative binomial distribution
r = 3
P = 30% = 0.3 probability of positive indication.
P(Y = 11) probability of 11 employees that must be tested to get 3 positives
Y-1Cr-1*p^r*q^(y-r)
Y-1 = 11-1 = 10
r-1 = 3 -1 = 2
10C2 x 0.3³x0.7⁸
45x0.027x0.05764801
= 0.070
This is the probability that 11 employees must be tested to get 3 positives.
