Can anyone help with the problems below?Please explain, if possible.

Calculate the following probabilities:

i. P(0£ z £ 2.3)

ii. P(0£ z £1.68)

iii. P(0.24£ z £.0.33)

iv. P(-2.58 £ z £ 0)

v. P(-2.81 £ z £. -1.35)

vi. P(-0.73 £ z £ 0.49)

vii. P(z ³ 1.7 )

viii. P(z ³ -0.95)

ix. P( z £ - 1.96) x. P(-1.4 £ z £ 1.55)

How do you work these out? I'm lost.
