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

The output of a plant is 4335 pounds of ball bearings per week (five days). If each ball bearing weighs 0.0113 g, how many ball

Setler79 [48]

Answer:

The plant makes 34,802,178 ball bearings in a single day

Step-by-step explanation:

The total output of a plant in a 5-day week is 4335 pounds

Each ball bearing weighs 0.0113g

We are to calculate the number of ball bearings made per day

First, we ensure both mass are in the same unit

Now 1 pound =453.5924 grams

4335 pounds=453.5924 X 4335 =1966323.054 grams

Number of bearings made in a week therefore

= 1966323.054 /0.0113=174010889.7

≈174010890 (to the nearest whole number)

Since there are 5 days in a week of production,

Daily Production=174010890/5

=34802178

The plant makes 34,802,178 ball bearings in a single da
