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](/tpl/images/0098/9668/8b64b.png)
So, we have to find![P(z\leq a)](/tpl/images/0098/9668/83852.png)
It is obvious that,
.
Also,![p(z\geq a)=1-0.7116=0.2884](/tpl/images/0098/9668/c5a55.png)
Hence, this is the required solution.
