Answer:
B) 0.02
Step-by-step explanation:
<u>Use the Binomial Theorem</u>

We have the probability of success,
, and the probability of failure,
. The binomial coefficient,
, represents the amount of possible combinations that
items can be chosen out of
items, with its respective formula
.
Hence, the best choice for the probability that 4 students chosen at random from the class of 30 that want the next test to be on Monday will be option B, 0.02
The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.
