A biased spinner has the numbers 1 2 3 4 what is the probability of getting a 4?
Without information about the bias, there can be no possible answer. You cannot even say that the probability of 4 is not 0.25 since suppose the spinner has the following probabilities: Pr(1) = 0.1 Pr(2) = 0.4 Pr(3) = 0.25 Pr(4) = 0.25 is clearly biased - in favour of 2, but the probability of 4 is not affected by the bias.
What is the probabilility that the spinner will land on six?
The probability that the spinner will land on six depends on how many numbers are on the spinner. If the spinner is only 1 through 6, then there is a 16.67% probability that the spinner will land on six with each spin.
What is the sample space of the spinner?
It depends on how many faces the spinner has. A six faced spinner could have a sample space of [1,2,3,4,5,6].
What is the probability that the spinner will land 5?
The answer depends on the shape of the spinner and the numbers on it.
What is the probability of the spinner not landing on 1 or 2?
The answer depends on the shape of the spinner and the numbers on it.
