Answer:
3/52
Step-by-step explanation:
The experimental probability of winning a free gallon of milk will be calculated as under -
It is given that, total number of outcomes = 156
Non-winning customers = 147 (it is given in the question)
Thus, the winning customers will be = Total outcomes - Non-winning customers
Expected winning customers = 156 - 147 = 9
The probability is calculated as -
Probability (Winning customer) = winning customers/total customers
Probability (Winning customer) = = 9/156 = 3/52
60 grams is the answer I think
Answer:
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Step-by-step explanation:
Given;
Confidence interval CI = (a,b) = (0.036, 0.086)
Lower bound a = 0.036
Upper bound b = 0.086
To express in the form;
p-e< p < p+e
Where;
p = mean Proportion
and
e = margin of error
The mean p =( lower bound + higher bound)/2
p = (a+b)/2
Substituting the values;
p = (0.036+0.086)/2
Mean Proportion p = 0.061
The margin of error e = (b-a)/2
Substituting the given values;
e = (0.086-0.036)/2
e = 0.025
Re-writing in the stated form, with p = 0.061 and e = 0.025
p-e< p < p+e
(0.061 - 0.025) < 0.061 < (0.061 + 0.025)
0.036 < 0.061 < 0.086
Solution: sum of all cards equals 50. Probability of not selecting a red card equals 12+20/50=32/50=16/25 B
You divide both sides by 14:
