Aquiz consists of 4 true-false questions. what is the probability of getting 100% on the quiz by randomly guessing the answer to all 4 questions?
Probability of guessing right on 4 in a row is 1/2 x 1/2 x 1/2 x 1/2 = 1/16
The probability of getting 100 % on the quiz is 0.0625.
Since we have given that
Number of true-false questions = 4
Number of chances of answer = 2
Probability of getting correct answer is given by
Probability of getting 100% on the quiz by randomly guessing the answer to all 4 questions is given by
Hence, The probability of getting 100 % on the quiz is 0.0625.
d. millimeters per hour.
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'.
