Answer:
a) 1/6
b) 1/36
c) 1/720
d) 1/3
Step-by-step explanation:
a) Any of the six comics can perform in the fourth place, so there is one chance in six that Comic F is the one that performs fourth.
b) In this case, we have two conditions. Both are independent of each other, so the probability of both happening is the product of the probabilities of each happening individually:
c) This combination is one in all possible orders of perform. The amount of combinations of orders is n!=6!=720 possible combinations. So the probability of this specific order is:
d) In this case, of the six possible comics performing in the last place, we calculate the probability of 2 of them being in that place. So the probability is:
Answer:
The z score for the airplane arriving 13 minutes after arrival time is 0.33
Step-by-step explanation:
Using normal distribution,
The average lateness for one of the top airline companies is 10 minutes. So our mean, u = 10
The variance, s of the lateness measure is calculated as 9.
x =13 which stands for arrival time.
Using normal distribution,
z = (x - u)/s
z = (13 - 10)/9 = 3/9 = 0.33
The z score for the airplane arriving 13 minutes after arrival time is 0.33. The probability value of the z score can be found by looking at the Normal distribution table

Answer:
11/4+3/6 =13/4or 3 1/4
Step-by-step explanation:
(11*6) + (3*4)
4*6
78/24
78/6=13
24/6=4
13/4 or 3 1/4
13/4=3 1/4
As the only prime factor of denominator is
2
, in fact there are three twos (
2

) we can can convert the fraction
7

by multiplying numerator and denominator by
5

.
Hence,

(This is always possible if only prime factors of denominator are
2
's and

's - just multiply by as many
5
's and
