Normal probabilities for jar masses, a shaded upper tail with its boundary, and an unknown mean from a lower percentage

The masses of honey in jars filled at a farm are normally distributed with mean \(340\) g and standard deviation \(6\) g.

1. A jar is chosen at random. Find the probability that the mass of honey in it is
   1. less than \(350\) g;
   2. between \(330\) g and \(350\) g.[4]

It is found that \(8\%\) of the jars contain more than \(d\) grams of honey.

2. 1. On the diagram above, mark \(d\) and shade the region that represents these jars.
   2. Find the value of \(d\).[5]

3. A second farm fills jars whose masses of honey are normally distributed with mean \(\mu\) g and standard deviation \(6\) g. Of these jars, \(10\%\) contain less than \(330\) g. Find the value of \(\mu\).[4]
