Answer:
65.3%
Step-by-step explanation:
Binomial distribution PMF below (along with a description)
the probabilty of getting 2, 3, or 4 successes in 5 trials is just
p(2)+p(3)+p(4)
p(2)= 5C2*.4²*(1-.4)³ = .3456
p(3)= 5C3*.4³*(1-.4)²= .2304
p(4)= 5C4*.4⁴*(1-.4)=.0768
.3456+.2304+.0768= .6528
Answer:
The answer is -10.
Step-by-step explanation:
4 - 5 - 9
-1 - 9
-10
Divide by -2: 3x-5 < -17
Add 5: 3x < -12
Divide by 3: x < -4 (answer)
