Find the probability of exactly three successes in six trials of a binomial experiment in which the the probability of is 50%.

posledela

Answer: 31.25%

Two ways to solve this problem:

#1: Use the formula: $P(X=x)={n}Cx_{} *p^{x}*(1-p)^{n-x}$

#2 Use a graphing calculator and use the function binompdf(n, p, x)

x = 3
n = 6
p = 0.5

#1: Formula:

$P(X=3)=_{6}C_{3}*0.5^{3} *(1-0.5)^{6-3}=\frac{6!}{3!(6-3)!} *0.5^{3} *0.5^{3}\\=\frac{6!}{3!*3!} *0.5^{3} *0.5^{3}=20*0.125*0.125=0.3125$

#2: Faster method

binompdf(6, 0.5, 3) = 0.3125

Which ordered pair is a solution to the system?

sweet-ann [11.9K]

Answer: C) (-3, -1)
X = -3 and y= -1

If you apply these values in the inequalities
y < 2x + 1
-3 < -2 + 1
-3 < -1
Since -3 is less than -1 , the values hold true for the first equation

y > -x-5
-3 > -1 - 5
-3 > -6
Since -3 is greater than -6, it also holds true for the 2nd equation
