Explanation / Answer

Normal Approximation to Binomial Distribution
Mean ( np ) =21 * 0.02 = 0.42
Standard Deviation ( npq )= 21*0.02*0.98 = 0.6416
Normal Distribution = Z= X- u / sd                   
P(X <= 2) = (2-0.42)/0.6416
= 1.58/0.6416= 2.4626
= P ( Z <2.4626) From Standard NOrmal Table
= 0.993

[ANSWER] it is 0.993
