1) We can simulate flipping a coin by generating random numbers from a uniform distribution
in [0,1) and considering numbers = 0.5 heads
Do the following in MA

The shape of the histogram should resemble and equal distribution of numbers. It does not have
this shape because there arent enough numbers that are plotted
