Which of the following is the probability of $x$ successes in a binomial distribution with number of trials $n$ and probability of success as $θ (0 <θ< 1)$ in each trial?

${^np}_xθ^x(1-θ)^{n-x},x=0,1,2,.....,n$ ${^nc}_xθ^x(1-θ)^{n-x},x=0,1,2,.....,n$ ${^nc}_xθ^x(1-θ),x=0,1,2,.....,n$ ${^nc}_xθ^x(1-θ)^{x},x=0,1,2,.....,n$

${^nc}_xθ^x(1-θ)^{n-x},x=0,1,2,.....,n$

$x$ → successes with $P=θ$ Probability = ${^nc}_x(θ)^x(1-θ)^{n-x}$
