how can i create Bernoulli random variable of a given probability

i have avalue of propability but i want to create a bernoulli random variable

P_LOS_1(i)=exp(-d(i)*lambda1);

x(i)=binornd(1,P_LOS_1(i));

P_NLOS1(i)=1-P_LOS1(i);

y(i)=binornd(1,P_NLOS_1(i));

If x(i) is one, y(i) MUST be zero and vice versa

but by this code it not true

i want to know what is error here ??

[Torsten]

p = 0.2;
n = 20000;
A = binornd(ones(n,1),p)

A = 20000×1

1 0 0 0 1 1 0 0 1 0

p_num = sum(A)/n

p_num = 0.2020

B = 1 - A

B = 20000×1

0 1 1 1 0 0 1 1 0 1

one_minus_p_num = sum(B)/n

one_minus_p_num = 0.7981
