Ran in:
Use randn to generate the sequences and modify it accordingly -
avg = 817e-9;
sd = 10e-9;
N = 50;
seq = avg + sd*randn(1, N)
seq = 1x50
1.0e-06 * 0.8245 0.7998 0.8200 0.8049 0.8297 0.8339 0.7922 0.8071 0.8122 0.8261 0.8032 0.8064 0.8150 0.8077 0.7972 0.8003 0.8210 0.8219 0.8206 0.8213 0.8189 0.8115 0.8254 0.8195 0.8034 0.8113 0.8140 0.8268 0.8225 0.8444

I am not sure about the probability, so I asked MATLAB AI Chat Playground about that and it provided the following -
seq(rand(1,N)>0.25) = 0
seq = 1x50
1.0e-06 * 0.8245 0 0 0 0.8297 0 0 0 0.8122 0 0 0 0 0 0 0.8003 0 0.8219 0 0.8213 0 0 0 0.8195 0 0 0.8140 0 0 0

@GULZAR, Normal distribution is just another name for Gaussian distribution.
