The probability that more than 5 students will pass their exam is 0.0188416.
<h3>How to find the probability?</h3>The probability that a student passes their examination = 40% = 0.4
The probability that more than 5 students pass their statistics exam = Probability that 6 students pass their exam + Probability that 7 students pass their exam
The probability that 6 students pass their exam =
The probability that 7 students pass their exam =
The probability that more than 5 students pass their statistics exam = 0.0172032 + 0.0016384
= 0.0188416
Therefore, we have found the probability that more than 5 students will pass their exam to be 0.0188416.

Answer: i guess the problem is with P(x) => "x = ", then P(x) is true if that equality is true, and is false if the equality is false.
so lets see case for case.
a) x = 0, and = 0. So p(0) is true.
b) x = 1 and = 1, so P(1) is true.
c) x = 2, and = 4, and 2 ≠ 4, then P(2) is false.
d) x= -1 and = 1, and 1 ≠ -1, so P(-1) is false.
Answer:
Step-by-step explanation:
I think it is a strangely worded question as they only refer to the larger gear turning.
I believe that this is what they are going for.
Number of teeth passing in each revolution
The Numbers match when the large gear turns two times as the smaller gear turns three times.
