Answer:
Question 1
probability of a red marble in the first draw = 1/10
probability of a orange marble in the second draw = 4/9
probability of getting red in first and orange in second (without replacement) = 1/10 * 4/9 = 2/45,
Question 2
6 outcomes
1/6
Answer: 0.067
Step-by-step explanation:
Binomial distribution formula :-
, here P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.
Given : n = 4 , p = 12 % = 0.12 and x =2
Then , 

∴ The probability of selecting two nonconforming units in the sample = 0.067

Answer:
16
Step-by-step explanation:
The largest square is 7-2 = 5 ratio units larger than the smaller square. Hence, each ratio unit stands for (10 cm)/5 = 2 cm. The side length of the smaller square is 2(2 cm) = 4 cm. The perimeter is 4 times that: 16 cm.
The perimeter of the smallest square is 16 cm.
