<span>The probability that a house in an urban area will develop a leak is 55%. if 20 houses are randomly selected, what is the probability that none of the houses will develop a leak? round to the nearest thousandth.
Use binomial distribution, since probability of developing a leak, p=0.55 is assumed constant, and
n=20, x=0
and assuming leaks are developed independently between houses,
P(X=x)
=C(n,0)p^x* (1-p)^(n-x)
=C(20,0)0.55^0 * (0.45^20)
=1*1*0.45^20
=1.159*10^(-7)
=0.000

Answer:
810
Step-by-step explanation:
The slope of y=-2x+5 is -2 the intercept is 5
Well, split it into 3 shapes
21 x 10 = 210
3 x 6 = 18
2 x 6 = 12
210 + 18 + 12 = 240 square cm
