- Length of a leaf The length of a leaf on a tree is a random variable with probability density function is defined by f(x)=332(4xx2)forxin[0,4]. a. Find the expected leaf length? b. Find for this distribution? c. Find the probability that the length of a given leaf is within 1 standard deviation of the expected value.arrow_forwardEarthquakes The proportion of the times in days between major earthquakes in the north-south seismic belt of China is a random variable that is exponentially distributed with a=1/609.5. a. Find the expected number of days and the standard deviation between major earthquakes for this region. b. Find the probability that the time between a major earthquake and the next one is more is than 1 year.arrow_forward
