For a standard normal distribution, if P(z<_a)=0.7116,what is the value of P(z<_a)?

0.2116
0.2884
0.7116
0.7884

Explanation :

A standard normal distribution table gives the information about the probability.

The normal distribution has mean is equal to zero and standard deviation is equal to 1.

In this case, it is given that
P(z\leq a)=0.7116

So, we have to find
P(z\leq a)

It is obvious that,
P(z\leq a)=0.7116.

Also,
p(z\geq a)=1-0.7116=0.2884

Hence, this is the required solution.
