Answer #1

solution

λ =50

P(X ≥ 60) =e-60/50

=0.3012

probability = 0.3012

    Recall that we assumed that the time between “likes” on this recent post is exponentially distributed with a mean of 10 “likes” every minute. Calculate the probability of observing exactly 10 likes in the first minute after the post is live and compare this to the probability of observing exactly 10 likes in the time interval between 48 hours after the post is live and 48 hours + 1 minute after the post is live. Does this match what you...
