A fraction is less than 1. Choose a counterexample that will prove this conjecture false
1 answer:
Answer:
1st option
Step-by-step explanation:
Here we are trying to prove that not all fractions are less than 1. So we have to choose an example in which the fraction is more than 1.
1)
This fraction is greater than 1 hence it can prove that the conjecture is false.
2) ½ is lesser than 1 and will not prove that the conjecture is false.

Answer:
The probability of getting exactly 2 soles is 0.375.
Step-by-step explanation:
The question is:
If you toss a fair coin 4 times, what's the probability that you get exactly 2 soles?
Solution:
A fair coin has two parts.
On tossing a coin once there is 50-50 odds of both the sides.
So, the probability of one side is, <em>p</em> = 0.50.
It is provided that a fair coin is tossed <em>n</em> = 4 times.
The event of any of the sides showing up after the toss are independent of each other.
The random variable <em>X</em> defined as soles, follows a Binomial distribution with parameters <em>n</em> = 4 and <em>p</em> = 0.50.
The probability mass function of <em>X</em> is:
Compute the probability of getting exactly 2 soles as follows:
Thus, the probability of getting exactly 2 soles is 0.375.
