Answer:22
Step-by-step explanation:27-5
Answer:
5%
Step-by-step explanation:
1 person will be selected out of a total of 20 (you + 19)
The probability is 1/20 = 0.05 = 5%
Substitute in the 3 points to find the values.
<span>P(0,8) = 3(0) + 2(8) = 16 </span>
<span>P(5,4) = 3(5) + 2(4) = 15 + 8 = 23 </span>
<span>P(9,0) = 3(9) + 2(0) = 27 </span>
<span>Therefore (9,0) is the maximum value. </span>
