[6] 3. Let z be the amount of time (in minutes) that a particular San Francisco commuter must wait for a BART train. Suppose that the density curve is as pictured Density 0.05 20 Minutes (a) What is the probability that is less than 5 minutes? (b) What is the probability that is between 10 and 12 minutes? 4/9 (c) Find the value c for which P(x <c) -0.9.
can someone help me solve both a and b?
Thanks.

PLEASE HELP! This is all the info that I am given. My lab has been moved to online class due to COVA-19 QUESTION 23: The coast of western Sumatra in Indonesia is a very seismically active area. In 2004, a magnitude 9.2 earthquake struck the region and generated a tsunami wave that caused massive destruction. In 2010, a magnitude 7.7 earthquake occurred in the same region, also generating a tsunami, albeit with less destruction than the one in 2004. Both...
