We'll use the formula for the classical probability as follows.
P(A) = Number of outcomes favorable for A / Total number of possible outcomes
In this case, two socks are randomly drawn from a set of 6+10 = 16 socks. So the total number of possible outcomes = 16C2 = 120.
The two stocks match each other if they are both blue or grey. So the number of favorable outcomes is 6C2 + 10C2 = 15 + 45 = 60.
Hence the probability that the two stocks match is

.
Answer:
x = 100
It is on a straight line and so, it equals to 180.
180 - 80 = 100
Answer: 100 rides are needed to break even.
Step-by-step explanation:
C(x)=15x+2000 - x is the number of rides.
R(x)=35 x , where x is the number of rides
35x=15x+2000
35-15x=2000~subtract 15x from both sides~
20x=2000 ~simplify~
x=2000/20 ~dividing both sides by 20~
x=100
Answer:
- x = 81 and 3/4
Step-by-step explanation:
8 × 2 – 4x = 363
16 - 4x = 363
Subtract 16 from each side:
16 - 16 - 4x = 363 - 16
- 4x = 327
Divide each side by 4:
- 4x ÷ 4 = 327 ÷ 4
- x = 81 and 3/4
Answer:
If a bag contains 4 red marbles, 3 blue marbles, and 7 green marbles and a marble is randomly selected from the bag, what is the probability that it is blue? P=3/(3+4+7)=3/14 because each of 14 marbles is equally likely to be drawn.
