Answer: The required probability is 0.1%.
Step-by-step explanation: Given that we have decided to play a Pick 3 lottery game in which we have to guess the exact order of the three numbers.
We are to find the probability of winning.
Let S denotes the sample space for choosing 3 numbers out of 10, .i.e., from 0 to 9. And A denote the event that we chose the exact order of the three numbers.
Since a number can be chosen more than once, so
Therefore, the probability of event A will be
Thus, the required probability is 0.1%.

Answer:
36
Step-by-step explanation:
The maximum height is the y-coordinate of the vertex
given a quadratic in standard form : ax² + bx + c : a ≠ 0
then the x-coordinate of the vertex is
= -
y = - x² + 20x - 64 is in standard form
with a = - 1, b = 20 and c = - 64, hence
= -
= 10
substitute x = 10 into the equation for y
y = - (10)² + 20(10) - 64 = 36 ← max height
