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
You can do
3 * 2 and 11 * 2 which would be 6:22 and is still equal to the ratio 3:11. Your explanation can be the when divided by 2 or the number you multiplied by, you would get the original ratio
Examples:
6:22
9:33
12:44
45 + 65 = 5m + 65
45 = 5m
m = 9
Answer:
Step-by-step explanation:
first the parenthesis
3^4/3^0=3^4
anything raised to the power of 0 is 1
(3^4)^2=3^8 you multiply the powers
3^-6 * 3^8= 3^(-6+8)=3^2
