Let z be a random variable with a standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.)
P(−1.21 ≤ z ≤ 2.63)=
P(z ≥ 1.33) =
P(z ≤ 1.25) =
P(z ≤ −0.22)=
P(−2.18 ≤ z ≤ −0.33) =

I'm not sure if you are expected to use a table, a handheld calculator, an online calculator or what.
I used an online calculator for the first, using z values between -1.21 and 2.63:
P(−1.21 ≤ z ≤ 2.63) = 0.8826
You can use the same calculator for the other values.
