Answer:
the probability that the ext order will be shrimp = 27.78%
Step-by-step explanation:
Vegetable 333
Chicken 666
Pork 222
Beef 222
Shrimp 555
total = 1,998
P (shrimp) = 555 / 1,998 = 0.2777 or 27.78%
in case the numbers in the orders were:
Vegetable 3
Chicken 6
Pork 2
Beef 2
Shrimp 5
total = 18
P (shrimp) = 5 / 18 = 0.2777 or 27.78%
The probability of an event happening is just the number of times that event occurred divided by the total number of events that took place.
Answer:
Step-by-step explanation:
Mp=$1200
Let sp be x
SP=MP-discount% of MP
x=1200-15/100 * 1200
x=120000-18000/100
x=102000/100
x=1020
the amount of money person saves=MP-SP
=$1200-$1020
=$180
therefore he saves $180
Answer:
a. 205320
b. 34220
c. 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
Step-by-step explanation:
a) The number of ways to dustribute exams among the TA's is:
n / (n - r)!
n= number of things to choose from
r= Choosing r number
60P3= 60! / (60 - 3)!
(60)(59)(58)(57)! / (57)!
=205320
B) The number of ways to dustribute the exams among the TA's is:
n! /(n - r)! r!
60C3= 60! /(60 - 3)! 3!
= 60!/ 57! 3!
= 60 × 59 × 58 / 3 × 2 × 1
= 34220
C) The required number of ways is:
60C25 + 60C20 + 60C15
= 60! / (35)! (25)! + 60!/ (40)!(20)! + 60!/ (45)! (15)!
