# S1 help normal distribution watch

1. P(-1.18<Z<1.43) so far I drew the graph !
2. It is the example on pg 178 example 1d)
3. Can you find P(Z< 1.43)?
4. Nvm I got it
5. OK - so we need to subtract P(Z< - 1.18), the lower 'tail'?

Which probability is this the same as?

Oh, do you mean you have sorted it?
6. (Original post by coolgamer)
P(-1.18<Z<1.43) so far I drew the graph !
Do you do the P(1.43) - P[1-P(1.18)]
to give 0.9426 - (1-0.8810) = 0.8236 or something or is my math wrong?
