Dividing the number of successful outcomes by the number of possible outcomes is the definition of the probability of the given event.
P(E)=n(E)/n(S)
example. let the Experiment be throwing a dice. The sample space, all the possible outcomes, is the set S={1, 2, 3, 4, 5, 6 } and n(S)=6
Let the even E be: getting an even number. The successful outcomes set is E {2, 4, 6 } and n(E)=3
So probability of getting an even number is P(E)=n(E)/n(S)=3/6=0.5
Answer: Probability of the given Event
Answer:
8
Step-by-step explanation:
The numbers are 6 and 2x, then:
- 1/6 + 1/(2x) = 7/24
- 1/3 + 1/x = 7/12
- (x+3)/(3x) = 7/12
- 12(x+3) = 7*3x
- 12x + 36 = 21x
- 21x - 12x = 36
- 9x = 36
- x = 4
The other number is 2*4 = 8
Answer:
not too much, you?
Step-by-step explanation:
Answer:
15.69% decrease
Step-by-step explanation:
To find the percent change, we take the original price and subtract the new price
2.55 -2.15 = .40
Divide by the original price
.40/2.55
.156862745
Multiply by 100%
15.6862745 %
Since the price went down, this is a decrease
15.69% decrease
26.to my knowledge no, I believe he is talking about perimeter so 7 3/8 + 7 3/8 = 14 6/8 or 14 12/16 and 5 1/16 +5 1/16= 10 2/16 so 14 12/16 +10 2/16 = 24 14/16 so she would be off by 14/16 because 2 feet =24 inchesxd 27. a 16 3/8 <m B.11 1/8 C.21 5/8
