Answer:
The probability that the selected ball is not blue is .
The probability that the selected ball is green is .
Step-by-step explanation:
The question is:
There are 10 brown balls, 5 blue balls and 15 green balls in a basket. If one is drawn at random, what is the probability that it is not blue? What is the probability that it is green?
Solution:
The probability of an event E is the ratio of the favorable number of outcomes to the total number of outcomes.
The probability of the given event not taking place is known as the complement of that event.
Complement of the event E is,
1 – P (E)
The number of different color balls are as follows:
Brown = n (Br) = 10
Blue = n (Bu) = 5
Green = n (G) = 15
Total = N = 30
Compute the probability of selecting a blue ball as follows:
Compute the probability of not selecting a blue ball as follows:
Thus, the probability that the selected ball is not blue is .
Compute the probability of selecting a green ball as follows:
Thus, the probability that the selected ball is green is .

B. 10
C. 21
O D. 11
TO
b) 180
c) 11
d) 405
Answer:
B is the answer
Step-by-step explanation:
Because we can make 4/6 into 2/3 and 2/3 of 270 is 180
friends. Keychains cost $2 each, and refrigerator magnets cost $1
each. Let x represent the number of keychains that Rosa bought,
and let y represent the number of refrigerator magnets.
Rosa bought 12 items and paid $18 more for the keychains than
for the refrigerator magnets.
9514 1404 393
Answer:
Step-by-step explanation:
We assume you want to know how many of each item Rosa bought.
The problem information lets us write two equations:
x + y = 12
2x - y = 18
Adding the two equations, we get ...
3x = 30
x = 10 . . . . . divide by 3
y = 12 -x = 2 . . . find y
Rosa bought 10 keychains and 2 magnets.
