First find all of the factors of 6. They are 1, 2, 3, and 6. The probability of anything is the number of possible outcomes divided by the total number of outcomes. The possible outcomes for factors of 6 are 1, 2, 3, and 6. There are 4. The total number of outcomes is 8, listing all of the integers 1-8. Therefore, the probability is 4/8 or 1/2. This can also be written as 50%.

Answer:
(c)
(b) The probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c) The probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
Step-by-step explanation:
The random variable <em>X</em> follows a Uniform (25, 35).
(a)
The probability density function of an Uniform distribution is:
Then the probability density function of the random variable <em>X</em> is:
(b)
Compute the value of P (X > 33) as follows:
Thus, the probability that time taken by Ayesha to prepare breakfast exceeds 33 minutes is 0.20.
(c)
Compute the mean of <em>X</em> as follows:
Compute the probability that cooking or preparation time is within 2 mins of the mean time as follows:
Thus, the probability that cooking or preparation time is within 2 mins of the mean time is 0.40.
