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:
Infinite
Step-by-step explanation:
3x+15=2x+10+x+5
grouping
3x+15=3x+15
If you have a equation where both sides are the exactly the same, the solutions are infinite. This is written as: x€ℝ
(7 and 7/16) is the simplest form.
5) 1.1802 x 10^6
6) 0.00016
7) 4.3 x 10^-3
8) 2,835,000
