I believe to find the range you just subtract the smallest from the largest:6.3-3.2=3.2
Answer:
C. 19.2 is the mean for this probability distribution.
Step-by-step explanation:
The mean for a probability distribution is ∑ P(x).x
Here, x∈{10, 20, 30, 40, 50}
P(10) × 10= 5.34
P(20) × 20=3.86
P(30) × 30=4.2
P(40) × 40=3.4
P(50) × 50=2.4
∑=5.34+3.86+4.2+3.4+2.4= 19.2
Therefore, the mean of this probability distribution is 19.2.
19 - 4.75 = 14.25
Your final price is 14.25 dollars.
