The value of f(-6) is -12.2
Explanation:
Given that the function
We need to determine the value of f(-6)
The value of f(-6) can be determined by substituting the value for in the function and simplify the function.
Hence, let us substitute in the function, we get,
Let us apply the rule , we get,
Multiplying the numbers, we get,
The value of
Substituting the value of , we get,
Subtracting the denominator, we have,
Dividing, we have,
Rounding off to the nearest tenth, we have,
Thus, the value of f(-6) is -12.2
The probability that the first two votes drawn are both for candidate a is given by:
3C2/5C2 = 3/10
Having drawn two votes for candidate a on the first two draws, there are 2 votes for candidate b and one vote for candidate a remaining. The probability that a vote for candidate b will be drawn on the third draw is:
2/3.
After the first three draws, there reains one vote for candidate a and one vote for candidate b. The probability that a vote for candidate a will be drawn on the fourth draw is:
1/2.
The probability of the ordering aabab is therefore given by:
The answer is: 0.1.
