Answer: 0.5143
Step-by-step explanation:
Probability of students who are over 21 years old = 30% = 0.3
Probability of students who are under 21 years old = 100% - 30% = 70% = 0.7
Probability of drinking alcohol for over 21 = 80% = 0.8
Probability of not drinking alcohol for over 21 = 100%- 80% = 20% = 0.2
Let the probability of the students who are not over 21, that drink alcohol be p.
Total probability of a college student drinking alcohol = (0.3 × 0.8) + (0.7 × p)
0.6 = (0.3 × 0.8) + (0.7 × p)
0.6 = 0.24 + 0.7p
0.7p = 0.6 - 0.24
0.7p = 0.36
p = 0.36/0.7
p = 0.5143
The probability of the students who are not over 21, that drink alcohol is 0.5143.

Answer:
X= (300 s + 200 b + 42 d )mg
Step-by-step explanation:
Amount of spinach=300 ml
Amount of berries =200 ml
amount of dressing = 42 ml
Vitamin C in one ml of spinach = s mg
Vitamin C in 300 ml of spinach = 300 s mg
Vitamin C in one ml of berries=b mg
Vitamin C in 200 ml of berries = 200 b mg
Vitamin C in one ml of dressing = d mg
Vitamin C in 42 ml of dressing = 42 d mg
Let total vitamin C be = x
Then
X= (300 s + 200 b + 42 d )mg
is the required expression
Answer:
1. The relative frequency of heads is (A) reasonably close to 40%.
2. Mr. Clark's claim about the theoretical probability is likely to be (A) True.
3. This means that the theoretical probability of tails is most likely 0.6 for this coin.
