please help

Hello there. Im strugling to do find the probabilty of (X >= 7),

where X ~ B(14; 0:55). Will it be binocdf(6,14,0.55)??

Also i found this in matlab's documentation :

Generate values from a normal distribution with mean 1 and standard deviation 2.

r = 1 + 2.*randn(100,1);

So this will create 100 numbers were the mean of all those number will be 1 and the standard deviation 2?

thanks in advance
