Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.
<h3>Calculating the mean.</h3>
Based on the information given, it should be noted that the probability distribution for y will be:
Y 0 1. 2
Probability 0.63. 0.25. 0.12
The mean of Y will be:
= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)
= 0 + 0.25 + 0.25
= 0.49
The variance will be 0.4899. Therefore, the standard deviation will be:
= ✓0.4899
= 0.699

The coordinates of the point after the two reflections are (0.3,-7/10).
<h3>What is the reflection?</h3>
A reflection is a mapping from an isometric hyperplane with a set of fixed points acting as the reflection's axis or plane from a Euclidean space to itself. A figure's reflection creates its mirror image of that figure in the plane or axis of the reflection.
Given that, the point (-0.3, 7/10) is reflected over the y-axis and then over the x-axis respectively.
The coordinates of the point after the reflection in the y-axis are:
(0.3, 7/10)
Now, the coordinates of the point after the reflection in the x-axis are:
(0.3, -7/10)
Hence, the coordinates of the point after the two reflections are (0.3,-7/10).
