No. 7/12 +1/4=7/12+ 3/12=10/12
10/12 is not 8/12
Using the binomial distribution, the mean number of balls you would expect him to catch is of 7.2.
<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
For this problem, the parameters are:
n = 8, p = 0.9.
Hence the mean is:
E(X) = np = 8 x 0.9 = 7.2.

Answer:
a) quantitative continuous
b) quantitative discrete
c) qualitative.
Step-by-step explanation:
Qualitative data is not numerical in nature but rather characterizes the data.
Quantitative discrete data is numerical but only have values in specific data points (for example, the whole numbers)
Quantitative continuous data is numerical and it can take values in all data points (meaning all real numbers)
Taken this in consideration let's proceed with the problem
a) The amount of fat in the breakfast bar is 2.4 grams:
This would be quantitative continuous because the fat can take all values from 0 to 2.4 and therefore it will be along the real numbers.
b) There were 126 students that signed up for Student Council:
This will be a quantitative discrete data. We will count up the number of students but we will only take whole numbers (there can not be 45.75 students signed up)
c) The leaders present at the conference were separated into Secretary, Treasurer and President.
In this case the data is not numerical and therefore is qualitative.
