Answer:
Part (a)
36
Part (b)
Find the filled table in the attachment
Part (c)
1/36
Step-by-step explanation:
The total number of possible outcomes using the multiplicative rule is given by;
6*6 = 36.
There are 6 possible outcomes in rolling each die, we simply find the product.
The probability of rolling double sixes is given by;
pr(6 and 6) = pr(6) * pr(6) = 1/6 * 1/6 = 1/36
The probability of rolling double sixes represents independent events and thus we employ the multiplicative rule of probability.
Step-by-step explanation:
f(3) = 48
f(3)-f(4) = 3*3^2
f(4) = 21
f(4)-f(5) = 3*4^2
f(5) = -27
Answer: 17 is the only prime number
Step-by-step explanation:
Answer:
0.01265
Step-by-step explanation:
Since, if the time to be served has an exponential distribution with a mean of 7, then

Chance to be served in under 2 minutes:

Let A represents the number of days when a person is served in less than 2 minutes,
Hence,
the probability that a person is served in less than 2 minutes on at least 5 of the next 7 days ( using binomial distribution )
= P(A=5) + P(A=6) + P(A=7)


≈ 0.01265
