Answer:
61.5%
Step-by-step explanation:
Let's find all the demographics first:
Sophomores in the class(total 15):
Female: 5
Male : 10
Freshmen in the class(total 11):
Female: 3
Male: 8
There are 11 freshmen(male and female) and 5 female sophomores. Thus, the probability of choosing one of these 16 people in a class of 26 is 16/26 or 61.5%.

2×2=4
2×3=6
2×4=8
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.
Answer:
$17
Step-by-step explanation:
since your finding retail price u need to do 10×.7 and that would be 7 then and the 7 to 10
Answer:
s>3
Step-by-step explanation:
Step 1: Flip the equation.
-4/3s <-4
Step 2: Multiply both sides by 3/(-4).
(3/-4) x (-4/3s) < (3/-4) x (-4)
s > 3
