The time it takes for a TV repair master to finish his job (in hours) has a density function of the form
f(x)={c(x-1)(x-2)0 if 1 a) Determine the constant c.
b) What is the probability that a TV repair master will finish the job
in less than 75 minutes? Between 3/2 and 2 hours?

answer is 12345678900987654321234567890987654321

step-by-step explanation:

in counting the number of heads in 4 coin flips, the probability that we get exactly one head is the probability that we get anyone of the following 4 outcomes: httt, thtt, ttht, or ttth. each has probability 1/16, so the probability to get exactly one head in 4 flips is 1/16 + 1/16 + 1/16 + 1/16 = 4/16 = 1/4.

raise 97 to the power of 6:
