Use binomial distribution, with p=0.20, n=20, x=3
P(X=x)=C(n,x)p^x (1-p)^(n-x)
P(X>=3)
=1-(P(X=0)+P(X=1)+P(X=2))
=1-(C(20,0)0.2^0 (0.8)^(20-0)+C(20,1)0.2^1 (0.8)^(20-1)+C(20,2)0.2^2 (0.8)^(20-2))
=1-(0.0115292+0.057646+0.136909)
=1-0.206085
=0.793915
Answer:
12 units
Step-by-step explanation:
(-7,-6)
if you reflect it over the x-axis then the second number would be changing
-6 the opposite is 6
(-7, 6)
from -6 to 6 is 12 jumps
12 units is the distance from the original point
Bust out a calculator my dear mammal!
600 +

Have a good one!
Benni OUT!
I think maybe 0.3 then 2 1/2 and then 15
