the probabiltity is:
outcome/total possible outcomes
therefore, 100/101
29
Note that consecutive numbers have a difference of 1 between them.
let n be the smallest integer then the three integers can be expressed as
n, n + 1 , n + 2
the sum is then
n + n + 1 + n + 2 = 90
3n + 3 = 90
subtract 3 from both sides of the equation
3n = 90 - 3 = 87
divide both sides by 3
n =
= 29
the three integers are 29, 30, 31 → the smallest is 29
7−4x+3=x−16−3x
Simplify
7−4x+3=x−16−3x
7+−4x+3=x+−16+−3x
(−4x)+(7+3)=(x+−3x)+(−16)(Combine Like Terms)
−4x+10=−2x+−16
−4x+10=−2x−16
Add 2x to both sides.
−4x+10+2x=−2x−16+2x
−2x+10=−16
Subtract 10 from both sides.
−2x+10−10=−16−10
−2x=−26
Divide both sides by -2.
−2x/−2=−26/−2
x=13
P(A) = 0.993 is the probability of event A
_
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)
Then, use the fact that the probability of A plus the probability not A is equal to 1:
_
=> P(A) + P(A) = 1
_
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007
So, the answers are:
_
1) P(A) = 0.07
_
2) Yes, A is unlikely because its probability is very low.
