Let Z be a standard normal random variable and calculate the following probabilities, drawing pictures wherever appropriate. (Round your answers to four decimal places.)

(a) P(0 <= Z <= 2.24)

(b) P(0 <= Z <= 2)

(c) P(%u22122.60 <= Z <= 0)

(d) P(%u22122.60 <= Z <= 2.60)

(e) P(Z <= 1.64)

(f) P(%u22121.75 <= Z)

(g) P(%u22121.60 <= Z <= 2.00)

(h) P(1.64 <= Z <= 2.50)

(i) P(1.60 <= Z)

(j) P(|Z| <= 2.50)

Please explain how to get the answer, I don't understand what the question is asking.
