I have a question on probability

Let z be a random variable with a standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.)

P(−0.86 ≤ z ≤ 0)
=

Let z be a random variable with a standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.)

P(−0.61 ≤ z ≤ 2.50)
=

Let z be a random variable with a standard normal distribution. Find the indicated probability. (Round your answer to four decimal places.)
P(z ≤ 1.18) =

P(−0.86 ≤ z ≤ 0)
= .3051

P(−0.61 ≤ z ≤ 2.50)
= .7229

P(z ≤ 1.18) = .8810

btw what's happened to your z-table ?
