Answer

The proportion of males wanting to be richer is $0.46$, and the proportion of females wanting to be richer is $0.41$.

Work Step by Step

We first locate the 'Richer' part in the graph. The blue bar represents male and the green bar represents female. The heights of the bars are then compared with the values of relative frequency on the vertical axis. The height of the blue bar corresponds to the value of $0.46$ on the left axis, while that of the green bar exceeds a little bit over $0.40$, probably would be $0.41$. That means the proportion of males wanting to be richer is $0.46$, and the proportion of females wanting to be richer is $0.41$.
