Probability and statistic problem

Suppose that the manufacturer a of a new medication wants to test the null hypothesis $\displaystyle \theta$ = 0.90 against the alternative hypothesis $\displaystyle \theta=0.60$ . His test statistic i X, the observed number of suces(recoveries) in 20 trials, and he will accept the null hypothesis if x>14 ; otherwise , he will rejext it.Find $\displaystyle \alpha$and $\displaystyle \beta$

Solution:

$\displaystyle \alpha$ =$\displaystyle P(X \leqq 14; \theta=0.90)=0.0114$

Please can anybody tell me hw did he get 0.0114 .If posible hw did u read the binomial table .Because i am not getting the answer.
