Answer:
0.0214
Step-by-step explanation:
Given that :
p = 5% = 0.05
Number of trials (n) = 5
probability that the sample contains exactly two defective parts
P(x = 2)
Using the binomial probability function :
P(x = x) = nCr * p^x * (1 - p)^(n-x)
P(x = 2) = 5C2 * 0.05^2 * (0.95)^3
P(x = 2) = 5C2 * 0.05^2 * (0.95)^3
P(x = 2) = 10 * 0.0025 * 0.857375
= 0.021434375
= 0.0214

Answer:
<em>$55,750 a</em>
Step-by-step explanation:
Given Principal P = $50,000
Rate R = 2.3%
Time T = 5 years
Get the interest first
Simple interest = PRT/100
Simple interest = 50,000*2.3*5/100
Simple interest = 500*2.3*5
Simple interest = $5,750
Amount = Principal + Interest
Amount = $50,000 + $5,750
Amount = $55,750
<em>Hence she will owe the bank $55,750 after 5 years</em>

Answer:
60%
Step-by-step explanation:
percentage of men in the choir = (4/11) x 100 = 36.4%
percentage of women in the choir = (7/11) x 100 = 63.6%
Percentage of men in the choir that prefer classical songs = 36.4 x0.25 = 9.1%
Percentage of women in the choir that prefer classical songs = 0.8 x 63.6% = 50.9%
percentage of the choir prefer classical songs = 50.9% + 9.1% = 60%
