Ten percent of all electrical batteries are defective. In a random selection of 8 of these batteries, find the probability that (a) There are no defective batteries. (b) More than 15 percent of the batteries are defective. (c) Between 8 and 12 percent of the batteries are defective. Suppose there was a random selection of n = 50 batteries in Prob. 2. Determine approximate probabilities for parts (a), (b), and (c) of that problem.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
