The denominator of the rational expression cannot be zero as this would make the rational expression undefined. Equating the denominator to zero and solving gives the value that m cannot be.

4m² = 0 ⇒ m² = 0 ⇒ m = 0 ← excluded value

Hi there,

I’m attaching the same image with more information on the graph.

The 4th mark (the middle dashed line) is marking the mean (70).

The 3rd and the 5th are marking the mean less/plus 1 deviation.

So, 70.5 is the 5th mark.

Taking this into account:

The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%

The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%

Good Luck!
