Answer:
Step-by-step explanation:
First, on the right-hand side of the equation, let's distribute the to each term in the parenthesis:
Now, let's move all the terms with an to the left-hand side, and everything else to the right-hand side of the equation:
Let's combine like terms:
Finally, let's divide each side by to get
by itself on the left-hand side of the equation:
Answer:
P = 0.041553
Step-by-step explanation:
Probability that a student considers calculus exciting. = 0.84
Probability that a student finds calculus not exciting = 0.16
This is a binomial experiment.
p = 0.84 and n = 29
The probability of observing 28 or more of the students who consider calculus to be an exciting subject in our sample of 29 is given by:
P = 0.041553
