The random variable X is exponentially distributed, where X represents the waiting time to see a shooting star during a meteor shower. If X has an average value of 71 seconds, what are the parameters of the exponential distribution?

λ=71, μ=71, σ=171

λ=171, μ=71, σ=71

λ=71, μ=171, σ=171

λ=271, μ=71, σ=712

λ=712, μ=71, σ=171

The random variable X is exponentially distributed, where X represents the waiting time to see a shooting star during a meteor shower.

X has an average value of 71 seconds.

parameters of exponential distribution:-

mean

[ because we know that for an exponential distribution mean() = standard deviation ()]

so, the parameters of exponential distribution are:
