A statistics teacher states the probability of a surprise quiz on any given day is 0.30. If quizzes are given independently of the day, what is the probability there will be a surprise quiz on the next two consecutive days?

0.09

Step-by-step explanation:

Given: The probability that a surprise quiz on any given day is 0.30.

Since quizzes are given independently of the day

Then, the probability there will be a surprise quiz on the next two consecutive days  = 0.30 x 0.30  [When events are independent then the probability of them both occurring is the product of the probabilities of each occurring. ]

= 0.09

Hence, the probability there will be a surprise quiz on the next two consecutive days =0.09
