Answer:
a) 0.0184
b) 0.1829
Step-by-step explanation:
a) With geometric distribution you can measure the number of trials until the first success, that is, a defective chip is found, as follows:
P(x = k) = p*(1-p)^(k-1)
This means: probability to find exactly 1 defective in k trials, p is the probability to find a defective chip, which is equal to 0.02, and the number of trials are k = 5. Replacing:
P(x = 5) = 0.02*(1-0.02)^(5-1) = 0.0184
b) If you want the probability of 1 success within k trials, compute:
Replacing with k = 10
Using the mean <u>formula and it's interpretation</u>, it is found that:
1. The mean is 7.52.
2. If we were to give this quiz to more and more students, the mean score for these students would approach 7.52.
The mean of a discrete distribution is given by the <u>sum of each outcome divided by it's respective probability</u>.
Hence, in this problem, according to the <u>distribution given</u>, the mean is:
The mean is 7.52.
The <em>interpretation </em>is that over many trials, the mean would approach 7.52.

Answer:
1. He earned 246
82% = 0.82
Move decimal right twice
82 x 300 is 24600
Move decimal left twice
= 246
2. 25
Solve for Y (Total Diamonds)
12 = 48% × Y
12 = 
× Y
Y = 12 × 
Y = 12 × 100 ÷ 48
Y = 25
3.80.95%
Solve for "%"
% = 34/42
% = 0.8095 (rounded)
Convert decimal to percent using percent formula:
% = 0.8095 × 100 = 80.95%
8*t^2 / 13*s is the correct answer
Hope this helps!
